DESCRIPTION:
Felix Wilhelm has reported a vulnerability in CakePHP, which can be
exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to the
cake/libs/controller/components/security.php script using
"unserialize()" with user controlled input. This can be exploited to
e.g. create a cache file with arbitrary PHP code using the
"__destruct()" method of a "App" class via a specially crafted
serialized object passed in a POST request.

The vulnerability is reported in versions prior to 1.2.9 and prior to
1.3.6.

SOLUTION:
Update to version 1.2.9 and 1.3.6.
