ID: 200501-36

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"
