Bug#777013: ax25-node: SIGQUIT fails
Package: ax25-node
Version: (all)
Severity: important
Dear Maintainer,
The SIGQUIT routine fails to close the app leaving the IP sockets open and in
some cases DDOS the remote site if a user "ctrl-]+q" out of a telnet session.
Also the app fails to close and more can be spawned by a crafty malicious user
thus bringing the system to a point of no memory available. I found this in
2005 with Barry K2MF and we incorporated a patch for MFNOS to prevent this from
attacking MFNOS.
Found this was the situation in ALL linux-based ax25 node packages. Patched
this in URONode and informed ax25-node upstream in 2007. No acknowledgement of
my email received to date.
Suggest replacing ax25-node with URONode for security reasons as other distros
have done.
