Update
=====

Version 6.3 of AWStats only partially fixed the input validation flaws. Furthermore, another flaw leading to unwanted information disclosure was found and fixed in AWStats.

The updated sections appear below.

Synopsis
=======

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

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-www/awstats < 6.3-r2 >= 6.3-r2

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. Furthermore, a user could read log file content even when plugin rawlog was not enabled.

Impact
=====

A remote attacker could supply AWStats malicious input, potentially allowing the execution of arbitrary code with the rights of the web server. He could also access raw log contents.

Resolution
=========

All AWStats users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-www/awstats-6.3-r2"

Note: Users with the vhosts USE flag set should manually use webapp-config to finalize the update.
