PHP < 5.2.14 / 5.3.x < 5.3.3 Multiple Vulnerabilities

Versions of PHP prior to 5.2.14, or 5.3.x prior to 5.3.3 are affected by the following vulnerabilities :

• An information disclosure vulnerability in ‘var_export()’ when a fatal error occurs.
• A resource destruction issue in ‘shm_put_var()’.
• A possible information leak because of an interruption of XOR operator.
• A memory corruption issue caused by an unexpected call-time pass by reference and the following memory clobbering through callbacks.
• A memory corruption issue in ‘ArrayObject::uasort()’.
• A memory corruption issue in ‘parse_str()’.
• A memory corruption issue in ‘pack()’.
• A memory corruption issue in ‘substr_replace()’.
• A memory corruption issue in ‘addcslashes()’.
• A stack exhaustion issue in ‘fnmatch()’.
• A buffer overflow vulnerability in the dechunking filter.
• An arbitrary memory access issue in the sqlite extension.
• A string format validation issue in the phar extension.
• An unspecified issue relating to the handling of session variable serialization on certain prefix characters.
• A NULL pointer dereference issue when processing invalid XML-RPC requests.
• An unserialization issue in ‘SplObjectStorage’.
• Buffer overflow vulnerabilities in ‘mysqlnd_list_fields’ and ‘mysqlnd_change_user’.
• Buffer overflows when handling error packets in mysqlnd.
• A flaw affects ‘sqlite_single_query()’ and ‘sqlite_array_query()’ methods included in the ‘ext/sqlite/sqlite.c’ source file. Specifically, the ‘rres’ resource is not properly initialized before use which may trigger a double-free condition when an empty query is passed to the ‘real_result_dtor()’ function.
