Descriptions

In Memcached before 1.6.22, a buffer overflow exists when processing multiget requests in proxy mode, if there are many spaces after the "get" substring.

It was discovered that Memcached incorrectly handled certain multiget requests in proxy mode. A remote attacker could use this issue to cause Memcached to crash, resulting in a denial of service, or possibly execute arbitrary code.
