The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2018:2789 advisory.

    The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with     extremely high determinism requirements.

    Security Fix(es):

    * A flaw named SegmentSmack was found in the way the Linux kernel handled specially crafted TCP packets. A     remote attacker could use this flaw to trigger time and calculation expensive calls to     tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() functions by sending specially modified packets within     ongoing TCP sessions which could lead to a CPU saturation and hence a denial of service on the system.
    Maintaining the denial of service condition requires continuous two-way TCP sessions to a reachable open     port, thus the attacks cannot be performed using spoofed IP addresses. (CVE-2018-5390)

    Red Hat would like to thank Juha-Matti Tilli (Aalto University - Department of Communications and     Networking and Nokia Bell Labs) for reporting this issue.

    Bug Fix(es):

    * The kernel-rt packages have been upgraded to the 3.10.0-693.39.1 source tree, which provides a number of     bug fixes over the previous version. (BZ#1616431)

    * Previously, preemption was enabled too early after a context switch. If a task was migrated to another     CPU after a context switch, a mismatch between CPU and runqueue during load balancing sometimes occurred.
    Consequently, a runnable task on an idle CPU failed to run, and the operating system became unresponsive.
    This update disables preemption in the schedule_tail() function. As a result, CPU migration during post-     schedule processing no longer occurs, which prevents the above mismatch. The operating system no longer     hangs due to this bug. (BZ#1618466)

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

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

This update for the Linux Kernel 3.12.74-60_64_63 fixes several issues.

The following security issues were fixed :

CVE-2018-5390: Prevent very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming TCP packet which can lead to a denial of service (bsc#1102682).

CVE-2018-10902: It was found that the raw midi kernel driver did not protect against concurrent access which lead to a double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status(), allowing a malicious local attacker to use this for privilege escalation (bsc#1105323).

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

This update for the Linux Kernel 3.12.61-52_146 fixes several issues.

The following security issues were fixed :

CVE-2018-14633: A security flaw was found in the chap_server_compute_md5() function in the ISCSI target code in the Linux kernel in a way an authentication request from an ISCSI initiator is processed. An unauthenticated remote attacker can cause a stack buffer overflow and smash up to 17 bytes of the stack. The attack requires the iSCSI target to be enabled on the victim host.
Depending on how the target's code was built (i.e. depending on a compiler, compile flags and hardware architecture) an attack may lead to a system crash and thus to a denial-of-service or possibly to a non-authorized access to data exported by an iSCSI target. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is highly unlikely. (bsc#1107832).

CVE-2018-5390: The Linux kernel could be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service (bsc#1102682).

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

The version of F5 Networks BIG-IP installed on the remote host is prior to 11.5.9 / 11.6.4 / 12.1.4.1 / 13.1.1.4 / 14.0.1.1 / 14.1.0. It is, therefore, affected by a vulnerability as referenced in the K95343321 advisory.

  - Linux kernel versions 4.9+ can be forced to make very expensive calls to tcp_collapse_ofo_queue() and     tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service. (CVE-2018-5390)

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

The SUSE Linux Enterprise 12 SP1 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2018-5390 aka 'SegmentSmack': A remote attacker even with relatively low bandwidth could have caused lots of CPU usage by triggering the worst case scenario during IP and/or TCP fragment reassembly (bsc#1102340)

CVE-2018-7191: In the tun subsystem in the Linux kernel, dev_get_valid_name was not called before register_netdevice. This allowed local users to cause a denial of service (NULL pointer dereference and panic) via an ioctl(TUNSETIFF) call with a dev name containing a / character. (bnc#1135603)

CVE-2018-20836: A race condition in smp_task_timedout() and smp_task_done() in drivers/scsi/libsas/sas_expander.c, could have lead to a use-after-free. (bnc#1134395)

CVE-2019-12614: An unchecked kstrdup might have allowed an attacker to cause denial of service (a NULL pointer dereference and system crash).
(bnc#1137194)

CVE-2019-12818: The nfc_llcp_build_tlv function in net/nfc/llcp_commands.c may have returned NULL. If the caller did not check for this, it would trigger a NULL pointer dereference. This would cause denial of service. (bnc#1138293)

CVE-2019-12456: An issue in the MPT3COMMAND case in _ctl_ioctl_main() allowed local users to cause a denial of service or possibly have unspecified other impact by changing the value of ioc_number between two kernel reads of that value, aka a 'double fetch' vulnerability.
(bsc#1136922)

CVE-2019-11487: An attacker could have triggered use-after-free via page reference count overflow on slow filesystems with at least of 140 GiB of RAM available. (bnc#1133190)

The update package also includes non-security fixes. See advisory for details.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Linux kernel versions 4.9+ can be forced to make very expensive calls to tcp_collapse_ofo_queue() and     tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service. (CVE-2018-5390)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:2384 advisory.

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

    Security Fix(es):

    * Modern operating systems implement virtualization of physical memory to efficiently use available system     resources and provide inter-domain protection through access control and isolation. The L1TF issue was     found in the way the x86 microprocessor designs have implemented speculative execution of instructions (a     commonly used performance optimisation) in combination with handling of page-faults caused by terminated     virtual to physical address resolving process. As a result, an unprivileged attacker could use this flaw     to read privileged memory of the kernel or other processes and/or cross guest/host boundaries to read host     memory by conducting targeted cache side-channel attacks. (CVE-2018-3620, CVE-2018-3646)

    * An industry-wide issue was found in the way many modern microprocessor designs have implemented     speculative execution of instructions past bounds check. The flaw relies on the presence of a precisely-     defined instruction sequence in the privileged code and the fact that memory writes occur to an address     which depends on the untrusted value. Such writes cause an update into the microprocessor's data cache     even for speculatively executed instructions that never actually commit (retire). As a result, an     unprivileged attacker could use this flaw to influence speculative execution and/or read privileged memory     by conducting targeted cache side-channel attacks. (CVE-2018-3693)

    * A flaw named SegmentSmack was found in the way the Linux kernel handled specially crafted TCP packets. A     remote attacker could use this flaw to trigger time and calculation expensive calls to     tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() functions by sending specially modified packets within     ongoing TCP sessions which could lead to a CPU saturation and hence a denial of service on the system.
    Maintaining the denial of service condition requires continuous two-way TCP sessions to a reachable open     port, thus the attacks cannot be performed using spoofed IP addresses. (CVE-2018-5390)

    * kernel: crypto: privilege escalation in skcipher_recvmsg function (CVE-2017-13215)

    * kernel: mm: use-after-free in do_get_mempolicy function allows local DoS or other unspecified impact     (CVE-2018-10675)

    * kernel: race condition in snd_seq_write() may lead to UAF or OOB access (CVE-2018-7566)

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3741-2 advisory.

    USN-3741-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04 LTS. This update provides the     corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu     14.04 LTS.

    It was discovered that memory present in the L1 data cache of an Intel CPU core may be exposed to a     malicious process that is executing on the CPU core. This vulnerability is also known as L1 Terminal Fault     (L1TF). A local attacker in a guest virtual machine could use this to expose sensitive information (memory     from other guests or the host OS). (CVE-2018-3646)

According to the versions of the cpupools / cpupools-features / etc packages installed, the Virtuozzo installation on the remote host is affected by the following vulnerabilities :

  - Modern operating systems implement virtualization of     physical memory to efficiently use available system     resources and provide inter-domain protection through     access control and isolation.

  - A flaw was found in Linux kernel's KVM virtualization     subsystem. The VMX code does not restore the GDT.LIMIT     to the previous host value, but instead sets it to     64KB. With a corrupted GDT limit a host's userspace     code has an ability to place malicious entries in the     GDT, particularly to the per-cpu variables. An attacker     can use this to escalate their privileges.

  - Use-after-free vulnerability in the snd_pcm_info()     function in the ALSA subsystem in the Linux kernel     allows attackers to induce a kernel memory corruption     and possibly crash or lock up a system. Due to the     nature of the flaw, a privilege escalation cannot be     fully ruled out, although we believe it is unlikely.

  - ALSA sequencer core initializes the event pool on     demand by invoking snd_seq_pool_init() when the first     write happens and the pool is empty. A user can reset     the pool size manually via ioctl concurrently, and this     may lead to UAF or out-of-bound access.

  - In the Linux kernel versions 4.12, 3.10, 2.6, and     possibly earlier, a race condition vulnerability exists     in the sound system allowing for a potential deadlock     and memory corruption due to use-after-free condition     and thus denial of service. Due to the nature of the     flaw, privilege escalation cannot be fully ruled out,     although we believe it is unlikely.

The SUSE Linux Enterprise 12 SP2 LTSS kernel was updated to receive various security and bugfixes. The following security bugs were fixed :

  - CVE-2018-3620: Local attackers on baremetal systems     could use speculative code patterns on hyperthreaded     processors to read data present in the L1 Datacache used     by other hyperthreads on the same CPU core, potentially     leaking sensitive data. (bnc#1087081).

  - CVE-2018-3646: Local attackers in virtualized guest     systems could use speculative code patterns on     hyperthreaded processors to read data present in the L1     Datacache used by other hyperthreads on the same CPU     core, potentially leaking sensitive data, even from     other virtual machines or the host system.
    (bnc#1089343).

  - CVE-2018-5390 aka 'SegmentSmack': The Linux Kernel can     be forced to make very expensive calls to     tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for     every incoming packet which can lead to a denial of     service (bnc#1102340).

  - CVE-2018-5391 aka 'FragmentSmack': A flaw in the IP     packet reassembly could be used by remote attackers to     consume lots of CPU time (bnc#1103097).

  - CVE-2018-14734: drivers/infiniband/core/ucma.c allowed     ucma_leave_multicast to access a certain data structure     after a cleanup step in ucma_process_join, which allowed     attackers to cause a denial of service (use-after-free)     (bnc#1103119).

  - CVE-2017-18344: The timer_create syscall implementation     in kernel/time/posix-timers.c didn't properly validate     the sigevent->sigev_notify field, which leads to     out-of-bounds access in the show_timer function (called     when /proc/$PID/timers is read). This allowed userspace     applications to read arbitrary kernel memory (on a     kernel built with CONFIG_POSIX_TIMERS and     CONFIG_CHECKPOINT_RESTORE) (bnc#1102851 bnc#1103580).

  - CVE-2018-9385: When printing the 'driver_override'     option from with-in the amba driver, a very long line     could expose one additional uninitialized byte     (bnc#1100491).

  - CVE-2018-13053: The alarm_timer_nsleep function in     kernel/time/alarmtimer.c had an integer overflow via a     large relative timeout because ktime_add_safe is not     used (bnc#1099924).

  - CVE-2018-13405: The inode_init_owner function in     fs/inode.c allowed local users to create files with an     unintended group ownership, in a scenario where a     directory is SGID to a certain group and is writable by     a user who is not a member of that group. Here, the     non-member can trigger creation of a plain file whose     group ownership is that group. The intended behavior was     that the non-member can trigger creation of a directory     (but not a plain file) whose group ownership is that     group. The non-member can escalate privileges by making     the plain file executable and SGID (bnc#1100416).

  - CVE-2018-13406: An integer overflow in the     uvesafb_setcmap function in     drivers/video/fbdev/uvesafb.c could result in local     attackers being able to crash the kernel or potentially     elevate privileges because kmalloc_array is not used     (bnc#1098016 1100418).

  - CVE-2018-5814: Multiple race condition errors when     handling probe, disconnect, and rebind operations could     be exploited to trigger a use-after-free condition or a     NULL pointer dereference by sending multiple USB over IP     packets (bnc#1096480).

The openSUSE Leap 42.3 kernel was updated to 4.4.143 to receive various security and bugfixes.

The following security bugs were fixed :

  - CVE-2017-18344: The timer_create syscall implementation     in kernel/time/posix-timers.c didn't properly validate     the sigevent->sigev_notify field, which leads to     out-of-bounds access in the show_timer function (called     when /proc/$PID/timers is read). This allowed userspace     applications to read arbitrary kernel memory (on a     kernel built with CONFIG_POSIX_TIMERS and     CONFIG_CHECKPOINT_RESTORE) (bnc#1102851 bnc#1103580).

  - CVE-2018-10876: A flaw was found in Linux kernel in the     ext4 filesystem code. A use-after-free is possible in     ext4_ext_remove_space() function when mounting and     operating a crafted ext4 image. (bnc#1099811)
