Synopsis:          Important: rsyslog7 security update
Advisory ID:       RHSA-2014:1654-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://access.redhat.com/errata/RHSA-2014:1654.html
Issue date:        2014-10-16
CVE Names:         CVE-2014-3634 
====================================================================
1. Summary:

Updated rsyslog7 packages that fix one security issue are now available for
Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having Important 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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64
Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64
Red Hat Enterprise Linux HPC Node (v. 6) - x86_64

3. Description:

The rsyslog7 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 or, potentially, execute arbitrary code as the user running
the rsyslog daemon. (CVE-2014-3634)

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

All rsyslog7 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.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/articles/11258
