"According to the version of the vzkernel package and the
readykernel-patch installed, the Virtuozzo installation on the remote
host is affected by the following vulnerabilities :

  - A double free vulnerability was found in netlink_dump,
    which could cause a denial of service or possibly other
    unspecified impact.

  - It was discovered that the Linux kernel since 3.6-rc1
    with 'net.ipv4.tcp_fastopen' set to 1 can hit BUG()
    statement in tcp_collapse() function after making a
    number of certain syscalls leading to a possible system
    crash.

  - A flaw was found in the way nfnetlink validated length
    of batch messages that could allow a user logged in to
    a container as root to cause a general protection fault
    and crash the host.

  - A flaw was found in the way nfnetlink handled errors
    while processing batch messages that could allow a user
    logged in to a container as root to trigger use after
    free and crash the host.

  - A security flaw was found in the Linux kernel that an
    attempt to move page mapped by AIO ring buffer to the
    other node triggers NULL pointer dereference at
    trace_writeback_dirty_page(), because
    aio_fs_backing_dev_info.dev is 0.

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

"An update for kernel is now available for Red Hat Enterprise Linux 7.

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) :

* It was found that the Linux kernel's IPv6 implementation mishandled
socket options. A local attacker could abuse concurrent access to the
socket options to escalate their privileges, or cause a denial of
service (use-after-free and system crash) via a crafted sendmsg system
call. (CVE-2016-3841, Important)

* Several Moderate and Low impact security issues were found in the
Linux kernel. Space precludes documenting each of these issues in this
advisory. Refer to the CVE links in the References section for a
description of each of these vulnerabilities. (CVE-2013-4312,
CVE-2015-8374, CVE-2015-8543, CVE-2015-8812, CVE-2015-8844,

Red Hat would like to thank Philip Pettersson (Samsung) for reporting
CVE-2016-2053; Tetsuo Handa for reporting CVE-2016-2847; the Virtuozzo
kernel team and Solar Designer (Openwall) for reporting CVE-2016-3156;
Justin Yackoski (Cryptonite) for reporting CVE-2016-2117; and Linn
Crosetto (HP) for reporting CVE-2016-3699. The CVE-2015-8812 issue was
discovered by Venkatesh Pottem (Red Hat Engineering); the
CVE-2015-8844 and CVE-2015-8845 issues were discovered by Miroslav
Vadkerti (Red Hat Engineering); the CVE-2016-4581 issue was discovered
by Eric W. Biederman (Red Hat); the CVE-2016-6198 issue was discovered
by CAI Qian (Red Hat); and the CVE-2016-3070 issue was discovered by
Jan Stancek (Red Hat).
