Description Jan Lieskovsky 2009-01-26 13:19:34 UTC
Untrusted search path vulnerability in the Python language bindings 
for Nautilus 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.

The Debian patch for similar dia's Python related issue,
available at:

http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=5;filename=pythonpath.diff;att=1;bug=504251

should be sufficient to resolve this issue.

Looks like the Python fix won't come anytime soon, so please
fix the issue in the package, till we find the proper Python solution.
