The array_user_key_compare function in PHP 4.4.6 and earlier, and 5.x up to 5.2.1, makes erroneous calls to zval_dtor, which triggers memory corruption and allows local users to bypass safe_mode and execute arbitrary code via a certain unset operation after array_user_key_compare has been called.

Security readout for executives and security teams

This is an old PHP memory-corruption flaw that could let a local user or hosted script escape PHP safe_mode controls and run arbitrary code. It matters mainly where legacy PHP 4.x or early 5.2 deployments still exist, especially shared hosting or multi-tenant systems. Exposure is likely limited to systems still running affected PHP versions or vendor packages derived from them. Internet exposure is indirect: an attacker would need a path to execute PHP locally, such as a hosted tenant account, compromised web application, or untrusted script execution. Treat this as high priority only for legacy PHP environments. Modern supported PHP deployments should not be affected based on the provided version range. For old shared-hosting, business risk is elevated because safe_mode bypass undermines tenant isolation. Mitigation focus: Inventory PHP runtimes and vendor PHP packages across servers.; Upgrade affected PHP versions using PHP or operating-system vendor advisories.; Retire reliance on safe_mode as a security boundary..
