CVE-2015-6834: Multiple use-after-free vulnerabilities in PHP before 5.4.45, 5.5.x before 5.5.29, and 5.6.x before 5.6.13...

Multiple use-after-free vulnerabilities in PHP before 5.4.45, 5.5.x before 5.5.29, and 5.6.x before 5.6.13 allow remote attackers to execute arbitrary code via vectors related to (1) the Serializable interface, (2) the SplObjectStorage class, and (3) the SplDoublyLinkedList class, which are mishandled during unserialization.

Security readout for executives and security teams

Older PHP 5.x releases contain memory-safety bugs that can let a remote attacker run code when serialized data is processed incorrectly. The strongest business concern is unsupported or legacy PHP handling untrusted input. The source bundle does not show active exploitation or a CVSS score. Exposure is most likely where PHP 5.4, 5.5, or 5.6 runtimes remain below the fixed versions, especially applications that process serialized PHP data from users, partners, queues, caches, or stored content. Treat as high priority for any legacy PHP estate. Remote code execution risk justifies rapid inventory and patching, but urgency should be driven by confirmed vulnerable versions and exposure to serialized input. Mitigation focus: Upgrade PHP to 5.4.45, 5.5.29, 5.6.13, or a fixed vendor package.; Apply relevant distribution advisories, including Debian DSA-3358 or Gentoo GLSA-201606-10 where applicable.; Check PHP upstream changelog and bug records for exact fixed release guidance..
