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.
