Description of problem:

When run with "-vv", on receipt of a binary-protocol deletion request, memcached prints out the key to be deleted in a way that can lead to a buffer overrun and crash.

Version-Release number of selected component (if applicable):

1.4.4, although this currently affects all later versions.

How reproducible:

Run memcached with "-vv", use memrm to send deletion requests and observe output.

Steps to Reproduce:

1. memcached -p 12345 -vv 2>&1 | grep '^Deleting' 2. memrm --servers localhost:12345 --binary ABCDEF xyz 3. Check the output from memcached.

Actual results:

[jsowden:~] $ memcached -p 2300 -m 64 -c 1024 -r -vv 2>&1 | grep 'Deleting' Deleting ABCDEF Deleting xyzDEF

Expected results:

[jsowden:~] $ memcached -p 2300 -m 64 -c 1024 -r -vv 2>&1 | grep 'Deleting' Deleting ABCDEF Deleting xyz
