AWStats fails to validate certain input, which could lead to the remote
execution of arbitrary code or to the leak of information.
AWStats is an advanced log file analyzer and statistics generator.
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
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.
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.
All AWStats users should upgrade to the latest version:
Code Listing 3.1: Resolution
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-misc/awstats-6.3-r2"
Note: Users with the vhosts USE flag set should manually use
webapp-config to finalize the update.
