The remote object store suffers from a weakness that may make buffer overflows easier to exploit.
The version of memcached / MemcacheDB running on the remote host reveals information about the stack, heap, and shared library memory locations it uses. An unauthenticated remote attacker may be able to leverage this weakness to defeat any address space layout randomization (ASLR) protection on the remote host, thereby making buffer overflows easier to exploit.
If using memcached, upgrade to version 1.2.8. If using MemcacheDB, upgrade to revision r98 or later from the code repository.
