Description Jan Lieskovsky 2009-01-26 06:16:49 EST
Untrusted search path vulnerability in gedit's Python module allows local
users to execute arbitrary code via a Trojan horse Python file in the
current working directory, related to an erroneous setting of sys.path
by the PySys_SetArgv function.

This issue affects all versions of the gedit package, as shipped
with Fedora releases of 9, 10 and devel.

Please fix.
Comment 5 Ray Strode [halfline] 2009-01-26 11:25:41 EST
I don't think this affects devel.

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=504352#4 mentions that python 2.6 isn't affected by this issue.  Will need to confirm, of course.

Drop into /tmp and run gedit from /tmp

Change argument passed to PySys_SetArgv

The eog patch referenced in comment 0 didn't seem to work when applied to gedit.  The above patch fixes it in a different way by ensuring that argv[0] always points to a valid location.
