NVD Description

Note: Versions mentioned in the description apply only to the upstream php-embedded package and not the php-embedded package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

The session deserializer in PHP before 5.4.45, 5.5.x before 5.5.29, and 5.6.x before 5.6.13 mishandles multiple php_var_unserialize calls, which allow remote attackers to execute arbitrary code or cause a denial of service (use-after-free) via crafted session content.
