The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2015:0695 advisory.

    The kernel packages contain the Linux kernel, the core of any Linux     operating system.

    * A flaw was found in the way the Linux kernel's SCTP implementation     validated INIT chunks when performing Address Configuration Change     (ASCONF). A remote attacker could use this flaw to crash the system by     sending a specially crafted SCTP packet to trigger a NULL pointer     dereference on the system. (CVE-2014-7841, Important)

    * It was found that the Linux kernel's Infiniband subsystem did not     properly sanitize input parameters while registering memory regions from     user space via the (u)verbs API. A local user with access to a     /dev/infiniband/uverbsX device could use this flaw to crash the system or,     potentially, escalate their privileges on the system. (CVE-2014-8159,     Important)

    * An integer overflow flaw was found in the way the Linux kernel's Frame     Buffer device implementation mapped kernel memory to user space via the     mmap syscall. A local user able to access a frame buffer device file     (/dev/fb*) could possibly use this flaw to escalate their privileges on the     system. (CVE-2013-2596, Important)

    * It was found that the parse_rock_ridge_inode_internal() function of the     Linux kernel's ISOFS implementation did not correctly check relocated     directories when processing Rock Ridge child link (CL) tags. An attacker     with physical access to the system could use a specially crafted ISO image     to crash the system or, potentially, escalate their privileges on the     system. (CVE-2014-5471, CVE-2014-5472, Low)

    Red Hat would like to thank Mellanox for reporting the CVE-2014-8159 issue.
    The CVE-2014-7841 issue was discovered by Liu Wei of Red Hat.

    This update also fixes the following bugs:

    * Previously, certain network device drivers did not accept ethtool     commands right after they were loaded. As a consequence, the current     setting of the specified device driver was not applied and an error message     was returned. The ETHTOOL_DELAY variable has been added, which makes sure     the ethtool utility waits for some time before it tries to apply the     options settings, thus fixing the bug. (BZ#1138299)

    * During the memory allocation for a new socket to communicate to the     server, the rpciod daemon released a clean page which needed to be     committed. However, the commit was queueing indefinitely as the commit     could only be provided with a socket connection. As a consequence, a     deadlock occurred in rpciod. This update sets the PF_FSTRANS flag on the     work queue task prior to the socket allocation, and adds the     nfs_release_page check for the flag when deciding whether to make a commit     call, thus fixing this bug. (BZ#1192326)

    All kernel users are advised to upgrade to these updated packages, which     contain backported patches to correct these issues. The system must be     rebooted for this update to take effect.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Updated kernel packages that fix two security issues and several bugs are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

* It was found that the Linux kernel's Infiniband subsystem did not properly sanitize input parameters while registering memory regions from user space via the (u)verbs API. A local user with access to a /dev/infiniband/uverbsX device could use this flaw to crash the system or, potentially, escalate their privileges on the system.
(CVE-2014-8159, Important)

* A use-after-free flaw was found in the way the Linux kernel's SCTP implementation handled authentication key reference counting during INIT collisions. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system.
(CVE-2015-1421, Important)

Red Hat would like to thank Mellanox for reporting the CVE-2014-8159 issue. The CVE-2015-1421 issue was discovered by Sun Baoliang of Red Hat.

This update also fixes the following bugs :

* In certain systems with multiple CPUs, when a crash was triggered on one CPU with an interrupt handler and this CPU sent Non-Maskable Interrupt (NMI) to another CPU, and, at the same time, ioapic_lock had already been acquired, a deadlock occurred in ioapic_lock. As a consequence, the kdump service could become unresponsive. This bug has been fixed and kdump now works as expected. (BZ#1197742)

* On Lenovo X1 Carbon 3rd Gen, X250, and T550 laptops, the thinkpad_acpi module was not properly loaded, and thus the function keys and radio switches did not work. This update applies a new string pattern of BIOS version, which fixes this bug, and function keys and radio switches now work as intended. (BZ#1197743)

* During a heavy file system load involving many worker threads, all worker threads in the pool became blocked on a resource, and no manager thread existed to create more workers. As a consequence, the running processes became unresponsive. With this update, the logic around manager creation has been changed to assure that the last worker thread becomes a manager thread and does not start executing work items. Now, a manager thread exists, spawns new workers as needed, and processes no longer hang. (BZ#1197744)

* If a thin-pool's metadata enters read-only or fail mode, for example, due to thin-pool running out of metadata or data space, any attempt to make metadata changes such as creating a thin device or snapshot thin device should error out cleanly. However, previously, the kernel code returned verbose and alarming error messages to the user. With this update, due to early trapping of attempt to make metadata changes, informative errors are displayed, no longer unnecessarily alarming the user. (BZ#1197745)

* When running Red Hat Enterprise Linux as a guest on Microsoft Hyper-V hypervisor, the storvsc module did not return the correct error code for the upper level Small Computer System Interface (SCSI) subsystem. As a consequence, a SCSI command failed and storvsc did not handle such a failure properly under some conditions, for example, when RAID devices were created on top of storvsc devices. An upstream patch has been applied to fix this bug, and storvsc now returns the correct error code in the described situation. (BZ#1197749)

All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

Updated kernel packages that fix two security issues and two bugs are now available for Red Hat Enterprise Linux 5.

Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

* It was found that the Linux kernel's Infiniband subsystem did not properly sanitize input parameters while registering memory regions from user space via the (u)verbs API. A local user with access to a /dev/infiniband/uverbsX device could use this flaw to crash the system or, potentially, escalate their privileges on the system.
(CVE-2014-8159, Important)

* An insufficient bound checking flaw was found in the Xen hypervisor's implementation of acceleration support for the 'REP MOVS' instructions. A privileged HVM guest user could potentially use this flaw to crash the host. (CVE-2014-8867, Important)

Red Hat would like to thank Mellanox for reporting CVE-2014-8159, and the Xen project for reporting CVE-2014-8867.

This update also fixes the following bugs :

* Under memory pressure, cached data was previously flushed to the backing server using the PID of the thread responsible for flushing the data in the Server Message Block (SMB) headers instead of the PID of the thread which actually wrote the data. As a consequence, when a file was locked by the writing thread prior to writing, the server considered writes by the thread flushing the pagecache as being a separate process from writing to a locked file, and thus rejected the writes. In addition, the data to be written was discarded. This update ensures that the correct PID is sent to the server, and data corruption is avoided when data is being written from a client under memory pressure. (BZ#1169304)

* This update adds support for new cryptographic hardware in toleration mode for IBM System z. (BZ#1182522)

All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-002050 advisory.

    The InfiniBand (IB) implementation in the Linux kernel package before 2.6.32-504.12.2 on Red Hat     Enterprise Linux (RHEL) 6 does not properly restrict use of User Verbs for registration of memory regions,     which allows local users to access arbitrary physical memory locations, and consequently cause a denial of     service (system crash) or gain privileges, by leveraging permissions on a uverbs device under     /dev/infiniband/.

The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2015-106:03 advisory.

    Description:
    The kernel package contains the Linux kernel (vmlinuz), the core of any     Linux operating system. The kernel handles the basic functions     of the operating system: memory allocation, process allocation, device     input and output, etc.
    Security issues fixed with this release:
    CVE-2014-7822
    ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when     announcing a new security problem. When the candidate has been publicized, the details for this candidate     will be provided.
    CVE-2014-8159
    ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when     announcing a new security problem. When the candidate has been publicized, the details for this candidate     will be provided.
    CVE-2014-8160     net/netfilter/nf_conntrack_proto_generic.c in the Linux kernel before 3.18 generates incorrect conntrack     entries during handling of certain iptables rule sets for the SCTP, DCCP, GRE, and UDP-Lite protocols,     which allows remote attackers to bypass intended access restrictions via packets with disallowed port     numbers.
    CVE-2014-8369     The kvm_iommu_map_pages function in virt/kvm/iommu.c in the Linux kernel through 3.17.2 miscalculates the     number of pages during the handling of a mapping failure, which allows guest OS users to cause a denial of     service (host OS page unpinning) or possibly have unspecified other impact by leveraging guest OS     privileges. NOTE: this vulnerability exists because of an incorrect fix for CVE-2014-3601.
    Fixed bugs:
    * The maximum amount of entries in the IPv6 route table (net.ipv6.route.max_size) was 4096, and every     route towards this maximum size limit was counted. Communication to more systems was impossible when the     limit was exceeded. Now, only cached routes are counted, which guarantees that the kernel does not run out     of memory, but the user can now install as many routes as the memory allows until the kernel indicates it     can no longer handle the amount of memory and returns an error message.
    In addition, the default net.ipv6.route.max_size value has been increased to 16384 for performance     improvement reasons.
    * When the user attempted to scan for an FCOE-served Logical Unit Number (LUN), after an initial LUN scan,     a kernel panic occurred in bnx2fc_init_task. With this update, fixed it.
    * Under certain conditions, such as when attempting to scan the network for LUNs, a race condition in the     bnx2fc driver could trigger a kernel panic in bnx2fc_init_task. With this update, fixed it.
    * Previously, it was not possible to boot the kernel on Xen hypervisor in PVHVM mode if more than 32 vCPUs     were specified in the guest configuration. Support for more than 32 vCPUs has been added, and fixed it.
    * When the NVMe driver allocated a namespace queue, it indicated that it was a request-based driver when     it was actually a block I/O-based driver. So, when NVMe driver was loaded along with a request-based dm     device, the system could terminate unexpectedly or become unresponsive when attempting to access data.
    With this update, fixed it.
    * If a user attempted to apply an NVRAM firmware update when running the tg3 module provided with Asianux     Server 4 SP4 kernels, the update could fail. So, the Network Interface Card (NIC) could stay in an     unusable state and this could prevent the entire system from booting. With this update, fixed it.
    * Support for key sizes of 256 and 192 bits has been added to AES-NI.

(CVE-2014-8159, Important)

* A flaw was found in the way the Linux kernel's splice() system call validated its parameters. On certain file systems, a local, unprivileged user could use this flaw to write past the maximum file size, and thus crash the system. (CVE-2014-7822, Moderate)

* A flaw was found in the way the Linux kernel's netfilter subsystem handled generic protocol tracking. As demonstrated in the Stream Control Transmission Protocol (SCTP) case, a remote attacker could use this flaw to bypass intended iptables rule restrictions when the associated connection tracking module was not loaded on the system.
(CVE-2014-8160, Moderate)

* It was found that the fix for CVE-2014-3601 was incomplete: the Linux kernel's kvm_iommu_map_pages() function still handled IOMMU mapping failures incorrectly. A privileged user in a guest with an assigned host device could use this flaw to crash the host.
(CVE-2014-8369, Moderate)

Red Hat would like to thank Mellanox for reporting CVE-2014-8159, and Akira Fujita of NEC for reporting CVE-2014-7822.

Bug fixes :

* The maximum amount of entries in the IPv6 route table (net.ipv6.route.max_size) was 4096, and every route towards this maximum size limit was counted. Communication to more systems was impossible when the limit was exceeded. Now, only cached routes are counted, which guarantees that the kernel does not run out of memory, but the user can now install as many routes as the memory allows until the kernel indicates it can no longer handle the amount of memory and returns an error message.

In addition, the default 'net.ipv6.route.max_size' value has been increased to 16384 for performance improvement reasons. (BZ#1177581)

* When the user attempted to scan for an FCOE-served Logical Unit Number (LUN), after an initial LUN scan, a kernel panic occurred in bnx2fc_init_task. System scanning for LUNs is now stable after LUNs have been added. (BZ#1179098)

* Under certain conditions, such as when attempting to scan the network for LUNs, a race condition in the bnx2fc driver could trigger a kernel panic in bnx2fc_init_task. A patch fixing a locking issue that caused the race condition has been applied, and scanning the network for LUNs no longer leads to a kernel panic. (BZ#1179098)

* Previously, it was not possible to boot the kernel on Xen hypervisor in PVHVM mode if more than 32 vCPUs were specified in the guest configuration. Support for more than 32 vCPUs has been added, and the kernel now boots successfully in the described situation. (BZ#1179343)

* When the NVMe driver allocated a namespace queue, it indicated that it was a request-based driver when it was actually a block I/O-based driver. Consequently, when NVMe driver was loaded along with a request-based dm device, the system could terminate unexpectedly or become unresponsive when attempting to access data. The NVMe driver no longer sets the QUEUE_FLAG_STACKABLE bit when allocating a namespace queue and device-mapper no longer perceives NVMe driver as request-based; system hangs or crashes no longer occur. (BZ#1180555)

* If a user attempted to apply an NVRAM firmware update when running the tg3 module provided with Red Hat Enterprise Linux 6.6 kernels, the update could fail. As a consequence, the Network Interface Card (NIC) could stay in an unusable state and this could prevent the entire system from booting. The tg3 module has been updated to correctly apply firmware updates. (BZ#1182903)

* Support for key sizes of 256 and 192 bits has been added to AES-NI.

The linux-2.6 update issued as DLA-246-1 caused regressions. This update corrects the defective patches applied in that update causing these problems. For reference the original advisory text follows.

This update fixes the CVEs described below.

CVE-2011-5321

Jiri Slaby discovered that tty_driver_lookup_tty() may leak a reference to the tty driver. A local user could use this flaw to crash the system.

CVE-2012-6689

Pablo Neira Ayuso discovered that non-root user-space processes can send forged Netlink notifications to other processes. A local user could use this flaw for denial of service or privilege escalation.

CVE-2014-3184

Ben Hawkes discovered that various HID drivers may over-read the report descriptor buffer, possibly resulting in a crash if a HID with a crafted descriptor is plugged in.

CVE-2014-8159

It was found that the Linux kernel's InfiniBand/RDMA subsystem did not properly sanitize input parameters while registering memory regions from user space via the (u)verbs API. A local user with access to a /dev/infiniband/uverbsX device could use this flaw to crash the system or, potentially, escalate their privileges on the system.

CVE-2014-9683

Dmitry Chernenkov discovered that eCryptfs writes past the end of the allocated buffer during encrypted filename decoding, resulting in local denial of service.

CVE-2014-9728 / CVE-2014-9729 / CVE-2014-9730 / CVE-2014-9731 / CVE-2015-4167

Carl Henrik Lunde discovered that the UDF implementation is missing several necessary length checks. A local user that can mount devices could use these various flaws to crash the system, to leak information from the kernel, or possibly for privilege escalation.

CVE-2015-1805

Red Hat discovered that the pipe iovec read and write implementations may iterate over the iovec twice but will modify the iovec such that the second iteration accesses the wrong memory. A local user could use this flaw to crash the system or possibly for privilege escalation.
This may also result in data corruption and information leaks in pipes between non-malicious processes.

CVE-2015-2041

Sasha Levin discovered that the LLC subsystem exposed some variables as sysctls with the wrong type. On a 64-bit kernel, this possibly allows privilege escalation from a process with CAP_NET_ADMIN capability; it also results in a trivial information leak.

CVE-2015-2042

Sasha Levin discovered that the RDS subsystem exposed some variables as sysctls with the wrong type. On a 64-bit kernel, this results in a trivial information leak.

CVE-2015-2830

Andrew Lutomirski discovered that when a 64-bit task on an amd64 kernel makes a fork(2) or clone(2) system call using int $0x80, the 32-bit compatibility flag is set (correctly) but is not cleared on return. As a result, both seccomp and audit will misinterpret the following system call by the task(s), possibly leading to a violation of security policy.

CVE-2015-2922

Modio AB discovered that the IPv6 subsystem would process a router advertisement that specifies no route but only a hop limit, which would then be applied to the interface that received it. This can result in loss of IPv6 connectivity beyond the local network.

This may be mitigated by disabling processing of IPv6 router advertisements if they are not needed: sysctl net.ipv6.conf.default.accept_ra=0 sysctl net.ipv6.conf.<interface>.accept_ra=0

CVE-2015-3339

It was found that the execve(2) system call can race with inode attribute changes made by chown(2). Although chown(2) clears the setuid/setgid bits of a file if it changes the respective owner ID, this race condition could result in execve(2) setting effective uid/gid to the new owner ID, a privilege escalation.

For the oldoldstable distribution (squeeze), these problems have been fixed in version 2.6.32-48squeeze12.

For the oldstable distribution (wheezy), these problems were fixed in linux version 3.2.68-1+deb7u1 or earlier, except for CVE-2015-1805 and CVE-2015-4167 which will be fixed soon.

For the stable distribution (jessie), these problems were fixed in linux version 3.16.7-ckt11-1 or earlier, except for CVE-2015-4167 which will be fixed later.

We recommend that you upgrade your linux-2.6 packages.

The SUSE Linux Enterprise Server 11 SP2 LTSS kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

  - CVE-2015-5707: An integer overflow in the SCSI generic     driver could be potentially used by local attackers to     crash the kernel or execute code.

  - CVE-2015-2830: arch/x86/kernel/entry_64.S in the Linux     kernel did not prevent the TS_COMPAT flag from reaching     a user-mode task, which might have allowed local users     to bypass the seccomp or audit protection mechanism via     a crafted application that uses the (1) fork or (2)     close system call, as demonstrated by an attack against     seccomp before 3.16 (bnc#926240).

  - CVE-2015-0777: drivers/xen/usbback/usbback.c in the     Linux kernel allowed guest OS users to obtain sensitive     information from uninitialized locations in host OS     kernel memory via unspecified vectors (bnc#917830).

  - CVE-2015-2150: Xen and the Linux kernel did not properly     restrict access to PCI command registers, which might     have allowed local guest users to cause a denial of     service (non-maskable interrupt and host crash) by     disabling the (1) memory or (2) I/O decoding for a PCI     Express device and then accessing the device, which     triggers an Unsupported Request (UR) response     (bnc#919463).

  - CVE-2015-5364: A remote denial of service (hang) via UDP     flood with incorrect package checksums was fixed.
    (bsc#936831).

  - CVE-2015-5366: A remote denial of service (unexpected     error returns) via UDP flood with incorrect package     checksums was fixed. (bsc#936831).

  - CVE-2015-1420: CVE-2015-1420: Race condition in the     handle_to_path function in fs/fhandle.c in the Linux     kernel allowed local users to bypass intended size     restrictions and trigger read operations on additional     memory locations by changing the handle_bytes value of a     file handle during the execution of this function     (bnc#915517).

  - CVE-2015-4700: A local user could have created a bad     instruction in the JIT processed BPF code, leading to a     kernel crash (bnc#935705).

  - CVE-2015-1805: The (1) pipe_read and (2) pipe_write     implementations in fs/pipe.c in the Linux kernel did not     properly consider the side effects of failed
    __copy_to_user_inatomic and __copy_from_user_inatomic     calls, which allowed local users to cause a denial of     service (system crash) or possibly gain privileges via a     crafted application, aka an 'I/O vector array overrun'     (bnc#933429).

  - CVE-2015-3331: The __driver_rfc4106_decrypt function in     arch/x86/crypto/aesni-intel_glue.c in the Linux kernel     did not properly determine the memory locations used for     encrypted data, which allowed context-dependent     attackers to cause a denial of service (buffer overflow     and system crash) or possibly execute arbitrary code by     triggering a crypto API call, as demonstrated by use of     a libkcapi test program with an AF_ALG(aead) socket     (bnc#927257).

  - CVE-2015-2922: The ndisc_router_discovery function in     net/ipv6/ndisc.c in the Neighbor Discovery (ND) protocol     implementation in the IPv6 stack in the Linux kernel     allowed remote attackers to reconfigure a hop-limit     setting via a small hop_limit value in a Router     Advertisement (RA) message (bnc#922583).

  - CVE-2015-2041: net/llc/sysctl_net_llc.c in the Linux     kernel used an incorrect data type in a sysctl table,     which allowed local users to obtain potentially     sensitive information from kernel memory or possibly     have unspecified other impact by accessing a sysctl     entry (bnc#919007).

  - CVE-2015-3636: The ping_unhash function in     net/ipv4/ping.c in the Linux kernel did not initialize a     certain list data structure during an unhash operation,     which allowed local users to gain privileges or cause a     denial of service (use-after-free and system crash) by     leveraging the ability to make a SOCK_DGRAM socket     system call for the IPPROTO_ICMP or IPPROTO_ICMPV6     protocol, and then making a connect system call after a     disconnect (bnc#929525).

  - CVE-2014-8086: Race condition in the     ext4_file_write_iter function in fs/ext4/file.c in the     Linux kernel allowed local users to cause a denial of     service (file unavailability) via a combination of a     write action and an F_SETFL fcntl operation for the     O_DIRECT flag (bnc#900881).

  - CVE-2014-8159: The InfiniBand (IB) implementation in the     Linux kernel did not properly restrict use of User Verbs     for registration of memory regions, which allowed local     users to access arbitrary physical memory locations, and     consequently cause a denial of service (system crash) or     gain privileges, by leveraging permissions on a uverbs     device under /dev/infiniband/ (bnc#914742).

  - CVE-2014-9683: Off-by-one error in the     ecryptfs_decode_from_filename function in     fs/ecryptfs/crypto.c in the eCryptfs subsystem in the     Linux kernel allowed local users to cause a denial of     service (buffer overflow and system crash) or possibly     gain privileges via a crafted filename (bnc#918333).

  - CVE-2015-2042: net/rds/sysctl.c in the Linux kernel used     an incorrect data type in a sysctl table, which allowed     local users to obtain potentially sensitive information     from kernel memory or possibly have unspecified other     impact by accessing a sysctl entry (bnc#919018).

  - CVE-2015-1421: Use-after-free vulnerability in the     sctp_assoc_update function in net/sctp/associola.c in     the Linux kernel allowed remote attackers to cause a     denial of service (slab corruption and panic) or     possibly have unspecified other impact by triggering an     INIT collision that leads to improper handling of     shared-key data (bnc#915577).
