The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2013:1490 advisory.

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

    * A flaw was found in the way IP packets with an Internet Header Length     (ihl) of zero were processed in the skb_flow_dissect() function in the     Linux kernel. A remote attacker could use this flaw to trigger an infinite     loop in the kernel, leading to a denial of service. (CVE-2013-4348,     Important)

    * A flaw was found in the way the Linux kernel's IPv6 implementation     handled certain UDP packets when the UDP Fragmentation Offload (UFO)     feature was enabled. A remote attacker could use this flaw to crash the     system or, potentially, escalate their privileges on the system.
    (CVE-2013-4387, Important)

    * A flaw was found in the way the Linux kernel handled the creation of     temporary IPv6 addresses. If the IPv6 privacy extension was enabled     (/proc/sys/net/ipv6/conf/eth0/use_tempaddr set to '2'), an attacker on     the local network could disable IPv6 temporary address generation, leading     to a potential information disclosure. (CVE-2013-0343, Moderate)

    * A flaw was found in the way the Linux kernel handled HID (Human Interface     Device) reports with an out-of-bounds Report ID. An attacker with physical     access to the system could use this flaw to crash the system or,     potentially, escalate their privileges on the system. (CVE-2013-2888,     Moderate)

    * Heap-based buffer overflow flaws were found in the way the     Pantherlord/GreenAsia game controller driver, the Logitech force feedback     drivers, and the Logitech Unifying receivers driver handled HID reports.
    An attacker with physical access to the system could use these flaws to     crash the system or, potentially, escalate their privileges on the system.
    (CVE-2013-2892, CVE-2013-2893, CVE-2013-2895, Moderate)

    * A NULL pointer dereference flaw was found in the way the N-Trig touch     screen driver handled HID reports. An attacker with physical access to the     system could use this flaw to crash the system, resulting in a denial of     service. (CVE-2013-2896, Moderate)

    * An information leak flaw was found in the way the Linux kernel's device     mapper subsystem, under certain conditions, interpreted data written to     snapshot block devices. An attacker could use this flaw to read data from     disk blocks in free space, which are normally inaccessible. (CVE-2013-4299,     Moderate)

    * A use-after-free flaw was found in the tun_set_iff() function in the     Universal TUN/TAP device driver implementation in the Linux kernel.
    A privileged user could use this flaw to crash the system or, potentially,     further escalate their privileges on the system. (CVE-2013-4343, Moderate)

    * An off-by-one flaw was found in the way the ANSI CPRNG implementation in     the Linux kernel processed non-block size aligned requests. This could lead     to random numbers being generated with less bits of entropy than expected     when ANSI CPRNG was used. (CVE-2013-4345, Moderate)

    * A flaw was found in the way the Linux kernel's IPv6 SCTP implementation     interacted with the IPsec subsystem. This resulted in unencrypted SCTP     packets being sent over the network even though IPsec encryption was     enabled. An attacker able to inspect these SCTP packets could use this flaw     to obtain potentially sensitive information. (CVE-2013-4350, Moderate)

    Red Hat would like to thank Fujitsu for reporting CVE-2013-4299 and Stephan     Mueller for reporting CVE-2013-4345. The CVE-2013-4348 issue was discovered     by Jason Wang of Red Hat.

    Bug fix:

    * RoCE appeared to be supported in the MRG Realtime kernel even when the     required user space packages from the HPN channel were not installed.
    The Realtime kernel now checks for the HPN channel packages before exposing     the RoCE interfaces. RoCE devices appear as plain 10GigE devices if the     needed HPN channel user space packages are not installed. (BZ#1012993)

    Users should upgrade to these updated packages, which upgrade the kernel-rt     kernel to version kernel-rt-3.8.13-rt14, and correct these issues.
    The system must be rebooted for this update to take effect.

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

Multiple vulnerabilities has been found and corrected in the Linux kernel :

The ipc_rcu_putref function in ipc/util.c in the Linux kernel before 3.10 does not properly manage a reference count, which allows local users to cause a denial of service (memory consumption or system crash) via a crafted application (CVE-2013-4483).

The skb_flow_dissect function in net/core/flow_dissector.c in the Linux kernel through 3.12 allows remote attackers to cause a denial of service (infinite loop) via a small value in the IHL field of a packet with IPIP encapsulation (CVE-2013-4348).

The Linux kernel before 3.12, when UDP Fragmentation Offload (UFO) is enabled, does not properly initialize certain data structures, which allows local users to cause a denial of service (memory corruption and system crash) or possibly gain privileges via a crafted application that uses the UDP_CORK option in a setsockopt system call and sends both short and long packets, related to the ip_ufo_append_data function in net/ipv4/ip_output.c and the ip6_ufo_append_data function in net/ipv6/ip6_output.c (CVE-2013-4470).

The ext4_orphan_del function in fs/ext4/namei.c in the Linux kernel before 3.7.3 does not properly handle orphan-list entries for non-journal filesystems, which allows physically proximate attackers to cause a denial of service (system hang) via a crafted filesystem on removable media, as demonstrated by the e2fsprogs tests/f_orphan_extents_inode/image.gz test (CVE-2013-2015).

net/ipv6/ip6_output.c in the Linux kernel through 3.11.4 does not properly determine the need for UDP Fragmentation Offload (UFO) processing of small packets after the UFO queueing of a large packet, which allows remote attackers to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact via network traffic that triggers a large response packet (CVE-2013-4387).

The IPv6 SCTP implementation in net/sctp/ipv6.c in the Linux kernel through 3.11.1 uses data structures and function calls that do not trigger an intended configuration of IPsec encryption, which allows remote attackers to obtain sensitive information by sniffing the network (CVE-2013-4350).

The updated packages provides a solution for these security issues.

The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2014-3046 advisory.

    - l2tp: fix an unprivileged user to kernel privilege escalation (Sasha Levin)  [Orabug: 19229497]     {CVE-2014-4943} {CVE-2014-4943}
    - ptrace,x86: force IRET path after a ptrace_stop() (Tejun Heo)  [Orabug: 19230689]  {CVE-2014-4699}

According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - The NFSv2 and NFSv3 server implementations in the Linux     kernel through 4.10.13 lacked certain checks for the     end of a buffer. A remote attacker could trigger a     pointer-arithmetic error or possibly cause other     unspecified impacts using crafted requests related to     fs/nfsd/nfs3xdr.c and     fs/nfsd/nfsxdr.c.(CVE-2017-7895i1/4%0

  - A flaw was found in the Linux kernel's ACPI subsystem     where a function does not flush the operand cache and     causes a kernel stack dump. This allows local users to     obtain sensitive information from kernel memory and     bypass the KASLR protection mechanism when using a     specially crafted ACPI table.(CVE-2017-13695i1/4%0

  - It was found that fanout_add() in     'net/packet/af_packet.c' in the Linux kernel, before     version 4.13.6, allows local users to gain privileges     via crafted system calls that trigger mishandling of     packet_fanout data structures, because of a race     condition (involving fanout_add and packet_do_bind)     that leads to a use-after-free bug.(CVE-2017-15649i1/4%0

  - Race condition in kernel/ucount.c in the Linux kernel     through 4.10.2 allows local users to cause a denial of     service (use-after-free and system crash) or possibly     have unspecified other impact via crafted system calls     that leverage certain decrement behavior that causes     incorrect interaction between put_ucounts and     get_ucounts.(CVE-2017-6874i1/4%0

  - An out-of-bounds memory access flaw, CVE-2014-7825, was     found in the syscall tracing functionality of the Linux     kernel's perf subsystem. A local, unprivileged user     could use this flaw to crash the system. Additionally,     an out-of-bounds memory access flaw, CVE-2014-7826, was     found in the syscall tracing functionality of the Linux     kernel's ftrace subsystem. On a system with ftrace     syscall tracing enabled, a local, unprivileged user     could use this flaw to crash the system, or escalate     their privileges.(CVE-2014-7825i1/4%0

  - The Salsa20 encryption algorithm in the Linux kernel,     before 4.14.8, does not correctly handle zero-length     inputs. This allows a local attacker the ability to use     the AF_ALG-based skcipher interface to cause a denial     of service (uninitialized-memory free and kernel crash)     or have an unspecified other impact by executing a     crafted sequence of system calls that use the     blkcipher_walk API. Both the generic implementation     (crypto/salsa20_generic.c) and x86 implementation     (arch/x86/crypto/salsa20_glue.c) of Salsa20 are     vulnerable.(CVE-2017-17805i1/4%0

  - The msm_ipc_router_bind_control_port function in     net/ipc_router/ipc_router_core.c in the IPC router     kernel module for the Linux kernel 3.x, as used in     Qualcomm Innovation Center (QuIC) Android contributions     for MSM devices and other products, does not verify     that a port is a client port, which allows attackers to     gain privileges or cause a denial of service (race     condition and list corruption) by making many     BIND_CONTROL_PORT ioctl calls.(CVE-2016-2059i1/4%0

  - The do_remount function in fs/namespace.c in the Linux     kernel through 3.16.1 does not maintain the     MNT_LOCK_READONLY bit across a remount of a bind mount,     which allows local users to bypass an intended     read-only restriction and defeat certain sandbox     protection mechanisms via a 'mount -o remount' command     within a user namespace.(CVE-2014-5206i1/4%0

  - The ati_remote2_probe function in     drivers/input/misc/ati_remote2.c in the Linux kernel     before 4.5.1 allows physically proximate attackers to     cause a denial of service (NULL pointer dereference and     system crash) via a crafted endpoints value in a USB     device descriptor.(CVE-2016-2185i1/4%0

  - 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-2014-8369i1/4%0

  - A NULL pointer dereference was found in     net/rds/rdma.c:__rds_rdma_map() function in the Linux     kernel allowing local attackers to cause a system panic     and a denial-of-service.(CVE-2018-7492i1/4%0

  - An issue was discovered in the XFS filesystem in     fs/xfs/xfs_icache.c in the Linux kernel. There is a     NULL pointer dereference leading to a system panic in     lookup_slow() on a NULL inode-i1/4zi_ops pointer when     doing pathwalks on a corrupted xfs image. This occurs     because of a lack of proper validation that cached     inodes are free during an allocation.(CVE-2018-13093i1/4%0

  - The iowarrior_probe function in     drivers/usb/misc/iowarrior.c in the Linux kernel before     4.5.1 allows physically proximate attackers to cause a     denial of service (NULL pointer dereference and system     crash) via a crafted endpoints value in a USB device     descriptor.(CVE-2016-2188i1/4%0

  - Linux kernel built with the 802.1Q/802.1ad     VLAN(CONFIG_VLAN_8021Q) OR Virtual eXtensible Local     Area Network(CONFIG_VXLAN) with Transparent Ethernet     Bridging(TEB) GRO support, is vulnerable to a stack     overflow issue. It could occur while receiving large     packets via GRO path, as an unlimited recursion could     unfold in both VLAN and TEB modules, leading to a stack     corruption in the kernel.(CVE-2016-7039i1/4%0

  - The msr_mtrr_valid function in arch/x86/kvm/mtrr.c in     the Linux kernel before 4.6.1 supports MSR 0x2f8, which     allows guest OS users to read or write to the     kvm_arch_vcpu data structure, and consequently obtain     sensitive information or cause a denial of service     (system crash), via a crafted ioctl     call.(CVE-2016-3713i1/4%0

  - A flaw was found in the way the Linux kernel's VFS     subsystem handled reference counting when performing     unmount operations on symbolic links. A local,     unprivileged user could use this flaw to exhaust all     available memory on the system or, potentially, trigger     a use-after-free error, resulting in a system crash or     privilege escalation.(CVE-2014-5045i1/4%0

  - The KEYS subsystem in the Linux kernel before 4.13.10     does not correctly synchronize the actions of updating     versus finding a key in the 'negative' state to avoid a     race condition, which allows local users to cause a     denial of service or possibly have unspecified other     impact via crafted system calls.(CVE-2017-15951i1/4%0

  - The skb_flow_dissect function in     net/core/flow_dissector.c in the Linux kernel through     3.12 allows remote attackers to cause a denial of     service (infinite loop) via a small value in the IHL     field of a packet with IPIP     encapsulation.(CVE-2013-4348i1/4%0

  - The Linux kernel through 3.17.4 does not properly     restrict dropping of supplemental group memberships in     certain namespace scenarios, which allows local users     to bypass intended file permissions by leveraging a     POSIX ACL containing an entry for the group category     that is more restrictive than the entry for the other     category, aka a 'negative groups' issue, related to     kernel/groups.c, kernel/uid16.c, and     kernel/user_namespace.c.(CVE-2014-8989i1/4%0

  - An infinite-loop flaw was found in the kernel. When a     local user calls the sys_writev syscall with a     specially crafted sequence of iov structs, the     fuse_fill_write_pages kernel function might never     terminate, instead continuing in a tight loop. This     process cannot be terminated and requires a     reboot.(CVE-2015-8785i1/4%0

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
