3. Description:

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.

4. Solution:

Before applying this update, make sure all previously-released errata
