PHP 4.x and 5.x before 5.2.1, when running on multi-threaded systems, does not ensure thread safety for libc crypt function calls using protection schemes such as a mutex, which creates race conditions that allow remote attackers to overwrite internal program memory and gain system access.

Security readout for executives and security teams

This old PHP flaw affects multi-threaded deployments using vulnerable PHP 4.x or PHP 5.x before 5.2.1. A thread-safety failure around libc crypt calls can corrupt memory. The reported impact is severe because remote attackers may gain system access, but the bundle provides no CVSS, CPEs, or current exploitation evidence. Exposure is most likely in legacy PHP applications still running PHP 4.x or PHP 5.x before 5.2.1 on multi-threaded web server configurations. Modern supported PHP versions should not be assumed affected from this bundle alone. Treat this as a legacy-risk cleanup item with high impact if present. It should be urgent only where obsolete PHP is still exposed, especially on internet-facing systems using multi-threaded hosting. Mitigation focus: Inventory PHP versions across all web and application servers.; Retire PHP 4.x and PHP 5.x before 5.2.1 where found.; Prioritize multi-threaded PHP hosting configurations for remediation..
