Note: Versions mentioned in the description apply only to the upstream php-gd package and not the php-gd package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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.
