Red Hat Security Advisory 2016-2128-01
Posted Oct 31, 2016
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2016-2128-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: A flaw was found in the Linux kernel's keyring handling code: the key_reject_and_link() function could be forced to free an arbitrary memory block. An attacker could use this flaw to trigger a use-after-free condition on the system, potentially allowing for privilege escalation.

                   Red Hat Security Advisory

Synopsis:          Important: kernel security and enhancement update
Advisory ID:       RHSA-2016:2128-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2016-2128.html
Issue date:        2016-10-31
CVE Names:         CVE-2016-4470 CVE-2016-5195 
=====================================================================

1. Summary:

An update for kernel is now available for Red Hat Enterprise Linux 6.6
Extended Update Support.

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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux HPC Node EUS (v. 6.6) - noarch, x86_64
Red Hat Enterprise Linux HPC Node Optional EUS (v. 6.6) - x86_64
Red Hat Enterprise Linux Server EUS (v. 6.6) - i386, noarch, ppc64, s390x, x86_64
Red Hat Enterprise Linux Server Optional EUS (v. 6.6) - i386, ppc64, s390x, x86_64

3. Description:

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

Security Fix(es):

* A flaw was found in the Linux kernel's keyring handling code: the
key_reject_and_link() function could be forced to free an arbitrary memory
block. An attacker could use this flaw to trigger a use-after-free
condition on the system, potentially allowing for privilege escalation.
(CVE-2016-4470, Important)

* 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)

Red Hat would like to thank Phil Oester for reporting CVE-2016-5195. The
CVE-2016-4470 issue was discovered by David Howells (Red Hat).

Enhancement(s):

* This update fixes a tape write problem by fixing the use of the
sas_is_tlr_enabled API in the mpt3sas driver. The driver now checks whether
Transport Layer Recovery (TLR) is enabled before enabling the
MPI2_SCSIIO_CONTROL_TLR_ON flag. (BZ#1372352)

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

The system must be rebooted for this update to take effect.

5. Bugs fixed (https://bugzilla.redhat.com/):

1341716 - CVE-2016-4470 kernel: Uninitialized variable in request_key handling causes kernel crash in error handling path
1384344 - CVE-2016-5195 kernel: mm: privilege escalation via MAP_PRIVATE COW breakage
