Description Tomas Hoger 2015-06-17 16:09:31 EDT

A type confusion issue was found in the way PHP performed unserialization of incomplete class.  If a specially crafted input is unserialized, it could lead to information leak and possibly code execution.

The issue was reported upstream in:

and was corrected in:

http://git.php.net/?p=php-src.git;a=commitdiff;h=fb83c76deec58f1fab17c350f04c9f042e5977d1
