An integer overflow vulnerability exists in memcached. This vulnerability is due to an integer overflow in the process_bin_update() function while processing multiple commands and the body_len parameter of a Memcached binary protocol packet. A remote unauthenticated attacker can exploit these vulnerabilities by sending a specially crafted packet to memcached. This can lead to a buffer overflow and possible code execution in the context of the user. If code execution is unsuccessful, a denial of service condition may result.
