Follow-up Comment #6, bug #63341 (group screen):

I had reported this issue in 2004 in the Debian BTS:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=273816

A server was running in GNU Screen, and I entered the copy/scrollback mode by
mistake (without noticing), yielding denial of service.

+1 for that version too.

In 2004 bug report, I also suggested a timeout option in case this is an
issue.
