memcached No Newline Memory Consumption DoS

Synopsis :

The remote object store has a denial of service vulnerability.

Description :

The version of memcached on the remote host has a denial of service
vulnerability. When processing a client request, the service
continually reads in new data, reallocating its input buffer until a
newline character is received. This could result in excessive
memory consumption.

A remote attacker could exploit this to crash memcached.
