rsyslog7 security update

CentOS Errata and Security Advisory CESA-2014:1654

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.
