The zend_restore_ini_entry_cb function in zend_ini.c in PHP 5.3.0, 5.2.10, and earlier versions allows context-specific attackers to obtain sensitive information (memory contents) and cause a PHP crash by using the ini_set function to declare a variable, then using the ini_restore function to restore the variable.

Security readout for executives and security teams

CVE-2009-2626 affects old PHP versions. Under specific conditions, an attacker who can influence PHP runtime configuration handling may expose process memory contents or crash PHP. Business urgency is highest for internet-facing or shared-hosting systems still running PHP 5.3.0, 5.2.10, or older. Exposure is mainly legacy PHP deployments, especially shared hosting, untrusted PHP execution environments, or applications where attackers can affect PHP code paths using ini configuration functions. Treat as a legacy technology risk. Prioritize remediation where old PHP supports revenue systems, public applications, or multi-tenant hosting. If no affected PHP remains, document non-exposure and close. Mitigation focus: Identify systems running PHP 5.3.0, 5.2.10, or earlier.; Upgrade PHP to a supported vendor-maintained release.; Apply relevant distribution security updates, including Debian guidance where applicable..
