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.
The attached patch should fix the problem.
---
The default allowWindowOps is false (as should be), but the man page
says the default is true. The man page should also mention that turning
it on is a security risk, to avoid regression e.g. as per
http://bugs.debian.org/384593
http://www.debian.org/security/2003/dsa-380
and also the much older
http://www.maths.usyd.edu.au/u/psz/securedu.html#xterm
(and private message to xterm maintainers on 9 Mar 2000, seems only
grep PSz main.c remains).
---
Ubuntu still allows window title reporting, and is vulnerable to
perl -e 'print \e\]0;;bad-command;\a\e\[21t'
---
I wonder whether the following are handled and/or dangerous:
set X property perl -e 'print \e\]3;XTerm.vt100.allowWindowOps=1\e\\'
set, get font perl -e 'print \e\]50;bad-command\e\\,\e\]50;?\e\\'
UDK setting perl -e 'print \eP1;1|17/0a6261642d636f6d6d616e640a\e\\'
then trick user to press F key, or
perl -e 'print \eP+q584b5f434f4c524f53\e\\'
