Synopsis
The remote CentOS 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.
Solution
