CVE-2005-1061: Logwatch

Medium severity, CVSS 5.0. EPSS: 3.1% chance of exploitation in the next 30 days.

The secure script in LogWatch before 2.6-2 allows attackers to prevent LogWatch from detecting malicious activity via certain strings in the secure file that are later used as part of a regular expression, which causes the parser to crash, aka "logwatch log processing regular expression DoS."

Affected products

• Logwatch Logwatch: version 2.6.2 only
• Red Hat Enterprise Linux: version 2.1 only
• Red Hat Linux Advanced Workstation: version 2.1 only
