Security readout for executives and security teams
CVE-2013-0191 is an authentication-bypass flaw in libpam-pgsql, also called pam_pgsql. If an exposed service relies on the affected PAM module, a remote attacker may be able to log in without valid credentials by abusing NULL password handling. The source bundle does not provide CVSS, confirmed exploitation, or a complete affected-version matrix. Exposure is limited to systems using libpam-pgsql/pam_pgsql for PAM authentication, especially network-facing services that authenticate users through PostgreSQL-backed PAM. Systems merely running PostgreSQL are not necessarily affected. Distribution packaging may differ, so confirm installed package names and vendor advisory status. Prioritize if the organization uses PostgreSQL-backed PAM for externally reachable or privileged services. The issue can affect login control, but scope is likely narrow and depends on deployment. Absence of active-exploitation evidence lowers emergency pressure, not remediation importance. Mitigation focus: Identify all systems using libpam-pgsql or pam_pgsql for PAM authentication.; Apply vendor updates referenced by the relevant distribution advisory where available.; Check upstream pam-pgsql guidance and commits before assuming a fixed version..
