Description
The (1) parse_str, (2) preg_match, (3) unpack, and (4) pack functions; the (5) ZEND_FETCH_RW, (6) ZEND_CONCAT, and (7) ZEND_ASSIGN_CONCAT opcodes; and the (8) ArrayObject::uasort method in PHP 5.2 through 5.2.13 and 5.3 through 5.3.2 allow context-dependent attackers to obtain sensitive information (memory contents) or trigger memory corruption by causing a userspace interruption of an internal function or handler. NOTE: vectors 2 through 4 are related to the call time pass by reference feature.
