    -------------------------------------------------------------------
     Package           /  Vulnerable  /                     Unaffected
    -------------------------------------------------------------------
  1  app-admin/analog      < 6.0-r2                          >=3D 6.0-r2

Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

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
=3D=3D=3D=3D=3D=3D

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
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

There is no known workaround at this time.

Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

All Analog users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=3Dapp-admin/analog-6.0-r2"

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