Description

Multiple use-after-free vulnerabilities in SPL in PHP before 5.4.44, 5.5.x before 5.5.28, and 5.6.x before 5.6.12 allow remote attackers to execute arbitrary code via vectors involving (1) ArrayObject, (2) SplObjectStorage, and (3) SplDoublyLinkedList, which are mishandled during unserialization.

Solution(s)

  • php-upgrade-5_4_44
  • php-upgrade-5_5_28
  • php-upgrade-5_6_12
