Description:   Opened: 2008-04-15 17:12 0000 
Bernhard R. Link has reported a security issue in rxvt, which can be exploited
by malicious, local users to gain escalated privileges.

The security issue is caused due to the program using ":0" as it's X11 display
if the DISPLAY environment variable is missing. This can be exploited to
execute arbitrary commands with the privileges of the user running rxvt via a
malicious X server.

The security issue is reported in version 2.6.4. Other versions may also be
affected.

Solution:
Do not run rxvt on untrusted systems.

Restrict local access to trusted users only.

D'oh, I managed to forget CC'ing arches as well.
Also CC'ing killerfox as he's probably interested in the patch because of bug
219760 (rxvt-unicode).

Patch sent upstream [1] (and added to this bug for completeness and so that I
could link to it).

Sorry for the arch cc'ing mess yesterday, btw (first I forgot to click "Add
archs", then I noticed that I missed release, then dirtyepic noticed I
accidently added mips...;)).
