Subject: CVE request: memcached DoS when printing out keys to be deleted in
 verbose mode

We got a report about a DoS in memcached when run with -vv (verbose
mode) and a request to delete a key is sent to the server (via memrm).
Because memcached doesn't null terminate the keys as it prints them,
fprintf may run off the end of the buffer.

This isn't a very significant issue (even without SSP/FORTIFY_SOURCE if
you could do something more malicious, memcached won't run as root).
Also note the docs indicate that memcached should only be accessible via
trusted users/hosts and not the internet at large, so the exposure
should be minimal.


Could a CVE be assigned for this?  Thanks.
