RHEL 6 : kernel (RHSA-2017:0869)

This script is Copyright (C) 2017 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

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.

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)
