Hello, Is a CVE needed for versions of libotr that support OTR v1? Quoting the Debian bug: "" as you are surely aware of, it's been known  since 2006 that clients supporting both OTRv1 and v2 (such as libotr 3.x) are subject to protocol downgrade attacks clients. It's also been known for a while that OTRv1 has serious security issues (that were the main reason for a v2, actually). In short, support v2 only is the only safe way to go these days.  http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.165.7945 "" Ubuntu advisory: http://www.ubuntu.com/usn/usn-2091-1/ Launchpad bug: https://bugs.launchpad.net/ubuntu/+source/libotr/+bug/1266016 Thanks, -- Murray McAllister / Red Hat Security Response Team  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=725779
