Description

with its own copy of bzip2, making it vulnerable to CVE-2008-1372 (GLSA

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 &quot;&gt;=app-admin/analog-6.0-r2&quot;

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