Created php tracking bugs for this issue: Affects: fedora-all [bug 1404737]
This issue happens when untrusted input is unserialized. Doing so is documented as being unsafe: http://php.net/manual/en/function.wddx-deserialize.php#refsect1-function.wddx-deserialize-notes Warning Do not pass untrusted user input to wddx_deserialize(). Unserialization can result in code being loaded and executed due to object instantiation and autoloading, and a malicious user may be able to exploit this.
