Synopsis
========

AWStats fails to validate certain input, which could lead to the remote
execution of arbitrary code.

Background
==========

AWStats is an advanced log file analyzer and statistics generator.

Affected packages
=================

    -------------------------------------------------------------------
     Package          /  Vulnerable  /                      Unaffected
    -------------------------------------------------------------------
  1  net-www/awstats        < 6.3                               >= 6.3

Description
===========

When 'awstats.pl' is run as a CGI script, it fails to validate specific
inputs which are used in a Perl open() function call.

Impact
======

A remote attacker could supply AWStats malicious input, potentially
allowing the execution of arbitrary code with the rights of the web
server.

Workaround
==========

Making sure that AWStats does not run as a CGI script will avoid the
issue, but we recommend that users upgrade to the latest version, which
fixes these bugs.

Resolution
==========

All AWStats users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-www/awstats-6.3"
