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"
