Analog: Denial of service

Background

Analog is a a webserver log analyzer.

Description

Diego E. Petteno reported that the Analog package in Gentoo is built with its own copy of bzip2, making it vulnerable to CVE-2008-1372 (GLSA 200804-02).

Impact

A local attacker could place specially crafted log files into a log directory being analyzed by analog, e.g. /var/log/apache, resulting in a crash when being processed by the application.

Workaround

There is no known workaround at this time.

Resolution

All Analog users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=app-admin/analog-6.0-r2"

NOTE: Analog is now linked against the system bzip2 library.
