Created php tracking bugs for this issue: Affects: fedora-all [bug 1377366] This issue happens when untrusted input is unserialized. Doing so it documented as being unsafe: http://php.net/manual/en/function.unserialize.php Do not pass untrusted user input to unserialize(). 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. Use a safe, standard data interchange format such as JSON (via json_decode() and json_encode()) if you need to pass serialized data to the user. |
