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.
