The remote host is vulnerable to a denial of service attack.
The remote host is running memcached, a distributed memory object caching system. The installed version of memcached is earlier than 1.4.3. Such versions are potentially affected by a denial of service vulnerability because the application continues to read in new data, reallocating its input buffer until a newline character is received which could lead to excessive memory consumption. An attacker, exploiting this flaw, could crash the affected service.
Upgrade to memcached 1.4.3 or later.
