Description Jan Lieskovsky 2009-01-26 10:40:31 UTC
Untrusted search path vulnerability in eog'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.

Comment 1 Jan Lieskovsky 2009-01-26 10:43:06 UTC
This issue does NOT affect the versions of the eog package, as shipped
with Red Hat Enterprise Linux 3, 4, and 5.

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

Please fix.

Comment 2 Jan Lieskovsky 2009-01-26 18:29:04 UTC
Affected file:

src/eog-python-module.c:        PySys_SetArgv (1, argv);

Comment 3 Tomas Hoger 2009-01-27 16:14:30 UTC
This should not be an issue for Fedora packages either, as they do not seem to be built with python support.  According to the build logs, affected file is not compiled at all.

$ curl -s http://kojipkgs.fedoraproject.org/packages/eog/2.24.3.1/1.fc10/data/logs/i386/build.log | grep --color 'Python support' 
checking whether Python support is requested... 
	Python support .............:  no

Similar for latest F11 build.

More explanation why this issue wasn't fixed in Python yet, can be
found here:

and here:

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.
