Description of problem: The php_binary serialization handler in the session extension in PHP before 4.4.5, and 5.x before 5.2.1, allows context-dependent attackers to obtain sensitive information (memory contents) via a serialized variable entry with a large length value, which triggers a buffer over-read.
This CVE name covered the issues mentioned in CVE-2007-0906 relating to the session extension. The fixes were originally included under the name CVE-2007-0906 in published errata, though the errata have now been updated to add the reference to CVE-2007-1380.
