Description |
PHP contains a flaw that may allow a remote attacker to cause a denial of service. The issue is due to the php_next_marker function in image.c, as reachable by the getimagesize PHP function, not properly sanitizing user-supplied input. By supplying a negative length value to the php_stream_seek, an attacker can cause an infinite loop and exhaust system resources.
