pam_sm_authenticate in pam_pgsql.c in libpam-pgsql 0.6.3 does not properly consider operator precedence when evaluating the success of a pam_get_pass function call, which allows local users to gain privileges via a SIGINT signal when this function is executing, as demonstrated by a CTRL-C sequence at a sudo password prompt in an "auth sufficient pam_pgsql.so" configuration.

Security readout for executives and security teams

CVE-2008-2516 is a local privilege risk in libpam-pgsql 0.6.3. In a specific PAM setup, a user at an authentication prompt may bypass expected authentication behavior by interrupting password handling. Business impact depends on whether systems still use this old PAM module and the risky configuration. Exposure is likely limited to Unix/Linux systems using libpam-pgsql 0.6.3 with pam_pgsql.so in PAM authentication stacks, especially auth sufficient configurations. The provided data does not identify broader affected versions or products. Treat as targeted cleanup rather than emergency response unless affected legacy systems are present. If pam_pgsql controls sudo or other privileged authentication paths, remediation should be prioritized because the business impact is privilege escalation on local systems. Mitigation focus: Inventory systems for libpam-pgsql 0.6.3 and pam_pgsql.so PAM usage.; Check Debian, project, and distribution guidance for fixed packages or configuration changes.; Prioritize PAM stacks using auth sufficient pam_pgsql.so for review..
