RHEL 5 / 6 : rsyslog5 and rsyslog (RHSA-2014:1671)

This script is Copyright (C) 2014-2017 Tenable Network Security, Inc.


Synopsis :

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

Description :

Updated rsyslog5 and rsyslog packages that fix one security issue are
now available for Red Hat Enterprise Linux 5 and 6 respectively.

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

The rsyslog packages provide an enhanced, multi-threaded syslog daemon
that supports writing to relational databases, syslog/TCP, RFC 3195,
permitted sender lists, filtering on any message part, and fine
grained output format control.

A flaw was found in the way rsyslog handled invalid log message
priority values. In certain configurations, a local attacker, or a
remote attacker able to connect to the rsyslog port, could use this
flaw to crash the rsyslog daemon. (CVE-2014-3634)

Red Hat would like to thank Rainer Gerhards of rsyslog upstream for
reporting this issue.

All rsyslog5 and rsyslog users are advised to upgrade to these updated
packages, which contain a backported patch to correct this issue.
After installing the update, the rsyslog service will be restarted
automatically.
