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.
