Summary
Red Hat Security Advisory: logwatch security update

Notes

Topic
An updated logwatch package that fixes one security issue is now available for Red Hat Enterprise Linux 5 and 6. The Red Hat Security Response Team 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.
Details
Logwatch is a customizable log analysis system. Logwatch parses through your system's logs for a given period of time and creates a report analyzing areas that you specify, in as much detail as you require. A flaw was found in the way Logwatch processed log files. If an attacker were able to create a log file with a malicious file name, it could result in arbitrary code execution with the privileges of the root user when that log file is analyzed by Logwatch. (CVE-2011-1018) Users of logwatch should upgrade to this updated package, which contains a backported patch to resolve this issue.
