GLSA 201203-20: Logwatch: Arbitrary code execution

Severity:high
Title:Logwatch: Arbitrary code execution
Date:03/28/2012
Bugs: #356387
ID:201203-20

Synopsis

A vulnerability in Logwatch might allow remote attackers to execute arbitrary code.

Background

Logwatch analyzes and reports on system logs.

Affected packages

Package Vulnerable Unaffected Architecture(s)
sys-apps/logwatch < 7.4.0 >= 7.4.0 All supported architectures

Description

logwatch.pl does not properly sanitize log filenames against shell metacharacters before passing them to the "system()" function.

Impact

A remote attacker could pass a specially crafted log filename to Logwatch, possibly resulting in execution of arbitrary code with root privileges or a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All Logwatch users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=sys-apps/logwatch-7.4.0"
