Package: xterm
Version: 222-1etch2
Severity: grave
Tags: security patch
Justification: user security hole
DECRQSS Device Control Request Status String "DCS $ q" simply echoes
(responds with) invalid commands. For example,
perl -e 'print "\eP\$q\nbad-command\n\e\\"'
would run bad-command.
Exploitability is the same as for the "window title reporting" issue
in DSA-380: include the DCS string in an email message to the victim,
or arrange to have it in syslog to be viewed by root.
Original:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=510030
Test:
perl -e 'print "\eP\$q\nwhoami\n\e\\"' > bla.log
cat bla.log
If whoami gets executed you should update.
So stop using cat or more ;)
