Red Hat Security Advisory
Synopsis: Moderate: kernel security and enhancement update
Advisory ID: RHSA-2017:0869-01
Product: Red Hat Enterprise Linux
Advisory URL: https://access.redhat.com/errata/RHSA-2017:0869
Issue date: 2017-04-04
CVE Names: CVE-2016-8399
=====================================================================
1. Summary:
An update for kernel is now available for Red Hat Enterprise Linux 6.7
Extended Update Support.
Red Hat Product Security has rated this update as having a security impact
of Moderate. 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. 6.7) - noarch, x86_64
Red Hat Enterprise Linux HPC Node Optional EUS (v. 6.7) - x86_64
Red Hat Enterprise Linux Server EUS (v. 6.7) - i386, noarch, ppc64, s390x, x86_64
Red Hat Enterprise Linux Server Optional EUS (v. 6.7) - 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 networking subsystem where a local attacker
with CAP_NET_ADMIN capabilities could cause an out-of-bounds memory access
by creating a smaller-than-expected ICMP header and sending to its
destination via sendto(). (CVE-2016-8399, Moderate)
Enhancement(s):
* Previously, the mpt3sas driver incorrectly checked the Transport Layer
Retries (TLR) state even on Redundant Array Of Independent Discs (RAID)
devices. Consequently, a kernel panic occurred when mpt3sas attempted to
read from the RAID devices. With this update, mpt3sas has been fixed to
check the TLR state only for non-RAID devices, and the kernel no longer
panics under the described circumstances. (BZ#1427459)
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/):
1403833 - CVE-2016-8399 kernel: net: Out of bounds stack read in memcpy_fromiovec
