The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2017:2760 advisory.

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

    Security Fix(es):

    * It was found that stacking a file system over procfs in the Linux kernel could lead to a kernel stack     overflow due to deep nesting, as demonstrated by mounting ecryptfs over procfs and creating a recursion by     mapping /proc/environ. An unprivileged, local user could potentially use this flaw to escalate their     privileges on the system. (CVE-2016-1583, Important)

    Bug Fix(es):

    * Previously, while the MAP_GROWSDOWN flag was set, writing to the memory which was mapped with the mmap     system call failed with the SIGBUS signal. This update fixes memory management in the Linux kernel by     backporting an upstream patch that enlarges the stack guard page gap. As a result, mmap now works as     expected under the described circumstances. (BZ#1474721)

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.

An update for kernel is now available for Red Hat Enterprise Linux 5.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

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

Security Fix(es) :

* A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged, local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system. (CVE-2016-5195, Important)

* It was found that stacking a file system over procfs in the Linux kernel could lead to a kernel stack overflow due to deep nesting, as demonstrated by mounting ecryptfs over procfs and creating a recursion by mapping /proc/environ. An unprivileged, local user could potentially use this flaw to escalate their privileges on the system.
(CVE-2016-1583, Important)

Red Hat would like to thank Phil Oester for reporting CVE-2016-5195.

Bug Fix(es) :

* In some cases, a kernel crash or file system corruption occurred when running journal mode 'ordered'. The kernel crash was caused by a NULL pointer dereference due to a race condition between two journal functions. The file system corruption occurred due to a race condition between the do_get_write_access() function and buffer writeout. This update fixes both race conditions. As a result, neither the kernel crash, nor the file system corruption now occur. (BZ#1067708)

* Prior to this update, some Global File System 2 (GFS2) files had incorrect time stamp values due to two problems with handling time stamps of such files. The first problem concerned the atime time stamp, which ended up with an arbitrary value ahead of the actual value, when a GFS2 file was accessed. The second problem was related to the mtime and ctime time stamp updates, which got lost when a GFS2 file was written to from one node and read from or written to from another node. With this update, a set of patches has been applied that fix these problems. As a result, the time stamps of GFS2 files are now handled correctly. (BZ#1374861)

The remote Ubuntu 14.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-2999-1 advisory.

    Jann Horn discovered that eCryptfs improperly attempted to use the mmap() handler of a lower filesystem     that did not implement one, causing a recursive page fault to occur. A local unprivileged attacker could     use to cause a denial of service (system crash) or possibly execute arbitrary code with administrative     privileges.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

  - CVE-2015-7515, CVE-2016-2184, CVE-2016-2185,     CVE-2016-2186, CVE-2016-2187, CVE-2016-3136,     CVE-2016-3137, CVE-2016-3138, CVE-2016-3140     Ralf Spenneberg of OpenSource Security reported that     various USB drivers do not sufficiently validate USB     descriptors. This allowed a physically present user with     a specially designed USB device to cause a denial of     service (crash).

  - CVE-2016-0821     Solar Designer noted that the list 'poisoning' feature,     intended to mitigate the effects of bugs in list     manipulation in the kernel, used poison values within     the range of virtual addresses that can be allocated by     user processes.

  - CVE-2016-1237     David Sinquin discovered that nfsd does not check     permissions when setting ACLs, allowing users to grant     themselves permissions to a file by setting the ACL.

  - CVE-2016-1583     Jann Horn of Google Project Zero reported that the     eCryptfs filesystem could be used together with the proc     filesystem to cause a kernel stack overflow. If the     ecryptfs-utils package is installed, local users could     exploit this, via the mount.ecryptfs_private program,     for denial of service (crash) or possibly for privilege     escalation.

  - CVE-2016-2117     Justin Yackoski of Cryptonite discovered that the     Atheros L2 ethernet driver incorrectly enables     scatter/gather I/O. A remote attacker could take     advantage of this flaw to obtain potentially sensitive     information from kernel memory.

  - CVE-2016-2143     Marcin Koscielnicki discovered that the fork     implementation in the Linux kernel on s390 platforms     mishandles the case of four page-table levels, which     allows local users to cause a denial of service (system     crash).

  - CVE-2016-3070     Jan Stancek of Red Hat discovered a local denial of     service vulnerability in AIO handling.

  - CVE-2016-3134     The Google Project Zero team found that the netfilter     subsystem does not sufficiently validate filter table     entries. A user with the CAP_NET_ADMIN capability could     use this for denial of service (crash) or possibly for     privilege escalation. Debian disables unprivileged user     namespaces by default, if locally enabled with the     kernel.unprivileged_userns_clone sysctl, this allows     privilege escalation.

  - CVE-2016-3156     Solar Designer discovered that the IPv4 implementation     in the Linux kernel did not perform the destruction of     inet device objects properly. An attacker in a guest OS     could use this to cause a denial of service (networking     outage) in the host OS.

  - CVE-2016-3157 / XSA-171     Andy Lutomirski discovered that the x86_64 (amd64) task     switching implementation did not correctly update the     I/O permission level when running as a Xen paravirtual     (PV) guest. In some configurations this would allow     local users to cause a denial of service (crash) or to     escalate their privileges within the guest.

  - CVE-2016-3672     Hector Marco and Ismael Ripoll noted that it was     possible to disable Address Space Layout Randomisation     (ASLR) for x86_32 (i386) programs by removing the stack     resource limit. This made it easier for local users to     exploit security flaws in programs that have the setuid     or setgid flag set.

  - CVE-2016-3951     It was discovered that the cdc_ncm driver would free     memory prematurely if certain errors occurred during its     initialisation. This allowed a physically present user     with a specially designed USB device to cause a denial     of service (crash) or possibly to escalate their     privileges.

  - CVE-2016-3955     Ignat Korchagin reported that the usbip subsystem did     not check the length of data received for a USB buffer.
    This allowed denial of service (crash) or privilege     escalation on a system configured as a usbip client, by     the usbip server or by an attacker able to impersonate     it over the network. A system configured as a usbip     server might be similarly vulnerable to physically     present users.

  - CVE-2016-3961 / XSA-174     Vitaly Kuznetsov of Red Hat discovered that Linux     allowed the use of hugetlbfs on x86 (i386 and amd64)     systems even when running as a Xen paravirtualised (PV)     guest, although Xen does not support huge pages. This     allowed users with access to /dev/hugepages to cause a     denial of service (crash) in the guest.

  - CVE-2016-4470     David Howells of Red Hat discovered that a local user     can trigger a flaw in the Linux kernel's handling of key     lookups in the keychain subsystem, leading to a denial     of service (crash) or possibly to privilege escalation.

  - CVE-2016-4482, CVE-2016-4485, CVE-2016-4486,     CVE-2016-4569, CVE-2016-4578, CVE-2016-4580,     CVE-2016-5243, CVE-2016-5244

    Kangjie Lu reported that the USB devio, llc, rtnetlink,     ALSA timer, x25, tipc, and rds facilities leaked     information from the kernel stack.

  - CVE-2016-4565     Jann Horn of Google Project Zero reported that various     components in the InfiniBand stack implemented unusual     semantics for the write() operation. On a system with     InfiniBand drivers loaded, local users could use this     for denial of service or privilege escalation.

  - CVE-2016-4581     Tycho Andersen discovered that in some situations the     Linux kernel did not handle propagated mounts correctly.
    A local user can take advantage of this flaw to cause a     denial of service (system crash).

  - CVE-2016-4805     Baozeng Ding discovered a use-after-free in the generic     PPP layer in the Linux kernel. A local user can take     advantage of this flaw to cause a denial of service     (system crash), or potentially escalate their     privileges.

  - CVE-2016-4913     Al Viro found that the ISO9660 filesystem implementation     did not correctly count the length of certain invalid     name entries. Reading a directory containing such name     entries would leak information from kernel memory. Users     permitted to mount disks or disk images could use this     to obtain sensitive information.

  - CVE-2016-4997 / CVE-2016-4998     Jesse Hertz and Tim Newsham discovered that missing     input sanitising in Netfilter socket handling may result     in denial of service. Debian disables unprivileged user     namespaces by default, if locally enabled with the     kernel.unprivileged_userns_clone sysctl, this also     allows privilege escalation.

Justin Yackoski discovered that the Atheros L2 Ethernet Driver in the Linux kernel incorrectly enables scatter/gather I/O. A remote attacker could use this to obtain potentially sensitive information from kernel memory. (CVE-2016-2117)

Hector Marco and Ismael Ripoll discovered that the Linux kernel would improperly disable Address Space Layout Randomization (ASLR) for x86 processes running in 32 bit mode if stack-consumption resource limits were disabled. A local attacker could use this to make it easier to exploit an existing vulnerability in a setuid/setgid program.
(CVE-2016-3672)

Andrey Konovalov discovered that the CDC Network Control Model USB driver in the Linux kernel did not cancel work events queued if a later error occurred, resulting in a use-after-free. An attacker with physical access could use this to cause a denial of service (system crash). (CVE-2016-3951)

It was discovered that an out-of-bounds write could occur when handling incoming packets in the USB/IP implementation in the Linux kernel. A remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2016-3955)

Kangjie Lu discovered an information leak in the ANSI/IEEE 802.2 LLC type 2 Support implementations in the Linux kernel. A local attacker could use this to obtain potentially sensitive information from kernel memory. (CVE-2016-4485)

    Jann Horn discovered that the extended Berkeley Packet Filter (eBPF) implementation in the Linux kernel     could overflow reference counters on systems with more than 32GB of physical ram and with RLIMIT_MEMLOCK     set to infinite. A local unprivileged attacker could use to create a use-after- free situation, causing a     denial of service (system crash) or possibly gain administrative privileges. (CVE-2016-4558)

    Jann Horn discovered that the InfiniBand interfaces within the Linux kernel could be coerced into     overwriting kernel memory. A local unprivileged attacker could use this to possibly gain administrative     privileges on systems where InifiniBand related kernel modules are loaded. (CVE-2016-4565)

    It was discovered that in some situations the Linux kernel did not handle propagated mounts correctly. A     local unprivileged attacker could use this to cause a denial of service (system crash). (CVE-2016-4581)
