Background ========== mod_auth_pgsql is an Apache2 module that allows user authentication against a PostgreSQL database. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-www/mod_auth_pgsql < 2.0.3 >= 2.0.3 Description =========== The error logging functions of mod_auth_pgsql fail to validate certain strings before passing them to syslog, resulting in format string vulnerabilities. Impact ====== An unauthenticated remote attacker could exploit these vulnerabilities to execute arbitrary code with the rights of the user running the Apache2 server by sending specially crafted login names. Workaround ========== There is no known workaround at this time. Resolution ========== All mod_auth_pgsql users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-www/mod_auth_pgsql-2.0.3" References ========== [ 1 ] CVE-2005-3656 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3656 [ 2 ] FrSIRT ADV-2006-0070 http://www.frsirt.com/english/advisories/2006/0070 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200601-05.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.
