CVE-2006-0056: Double free vulnerability in the authentication and authentication token alteration code in PAM-MySQL 0.6.x...

Double free vulnerability in the authentication and authentication token alteration code in PAM-MySQL 0.6.x before 0.6.2 and 0.7.x before 0.7pre3 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via crafted passwords, which lead to a double free of a pointer that was created by the pam_get_item function. NOTE: this issue only occurs in certain configurations in which there are multiple PAM modules, PAM-MySQL is not evaluated first, and there are no requisite modules before PAM-MySQL.

Security readout for executives and security teams

This flaw affects PAM-MySQL, an older authentication module. In specific PAM stack configurations, a crafted password could crash authentication and may allow code execution. Business risk is highest where legacy Linux systems still use vulnerable PAM-MySQL versions for remote login or application authentication. Exposure is likely limited to legacy systems still running PAM-MySQL 0.6.x or early 0.7.x, especially with multiple PAM modules where PAM-MySQL is not evaluated first and no earlier module is marked requisite. Treat as a targeted legacy cleanup item. It is not KEV-listed, but authentication crashes and possible code execution justify prompt remediation where PAM-MySQL is still deployed. Mitigation focus: Upgrade PAM-MySQL to 0.6.2, 0.7pre3, or a vendor-fixed later package.; Check distribution advisories, including Gentoo GLSA-200606-18, for package-specific guidance.; Identify systems using PAM-MySQL in authentication stacks..
