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" References ========== [ 1 ] AWStats ChangeLog http://awstats.sourceforge.net/docs/awstats_changelog.txt [ 2 ] iDEFENSE Advisory http://www.idefense.com/application/poi/display?id=185 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200501-36.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
