Bug#518511: krfb: crash (SIGABRT) after disconnect
Subject: krfb: crash (SIGABRT) after disconnect
Followup-For: Bug #518511
Package: krfb
Version: 4:3.5.10-2
Hello,
this issue is also replicable on Debian Lenny.
The crash happens about 5 seconds after disconnecting the session. It
happens on every disconnect.
It also happens by aborting the password prompt, without entering a
valid password. If the problem happens then it's no longer possible to
connect to the PC using VNC which means that this is also a Denial of
Service issue.
It would be good to get it fixed in Lenny.
Thanks,
Andreas
