Description Vincent Danen 2012-03-20 20:15:27 UTC 
It was reported [1] that Bitlbee did not drop group privileges correctly.  Bitlbee is supposed to drop privileges, but it simply calls setgid() followed by setuid() which is insufficient, as the extra groups the process was started with are still available.

This is corrected upstream [2] (although the changeset r856 includes some unrelated fixes as well; the patch to unix.c is the required fix).  Bitlbee 3.0.4 is affected.
