Double free vulnerability in the unserializer in PHP 4.4.5 and 4.4.6 allows context-dependent attackers to execute arbitrary code by overwriting variables pointing to (1) the GLOBALS array or (2) the session data in _SESSION. NOTE: this issue was introduced when attempting to patch CVE-2007-1701 (MOPB-31-2007).

Security readout for executives and security teams

CVE-2007-1711 is an old PHP memory-corruption flaw. On PHP 4.4.5 and 4.4.6, certain serialized data handling can corrupt memory and may let an attacker run code. Business risk is mainly legacy systems that still run these PHP versions or vendor packages based on them. Exposure is most likely in legacy PHP 4.4.5 or 4.4.6 deployments, especially applications processing serialized data or session state. Modern supported PHP stacks are unlikely to be affected unless old bundled PHP packages remain present. Prioritize remediation if any legacy PHP 4.4.5 or 4.4.6 systems remain in production. The issue is old, but arbitrary code execution in a web runtime can be severe. Treat unsupported PHP as a broader operational risk. Mitigation focus: Identify and retire PHP 4.4.5 and 4.4.6 runtimes.; Apply relevant vendor security advisories for affected distributions.; Upgrade legacy applications to a supported PHP branch..
