TITLE:
Tofu Game Engine Arbitrary Python Code Execution Vulnerability

SECUNIA ADVISORY ID:
SA16876

VERIFY ADVISORY:
http://secunia.com/advisories/16876/

CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:
>From local network

SOFTWARE:
Tofu 0.x
http://secunia.com/product/5735/

DESCRIPTION:
Arc Riley has reported a vulnerability in Tofu, which can be
exploited by malicious people to compromise a user's system.

The vulnerability is caused to a design error in the handling of
serialized Python objects (pickles) sent from other clients. This can
be exploited to execute arbitrary Python code in a network game that
uses Tofu, via specially crafted classes.

The vulnerability has been reported in version 0.2. Prior versions
may also be affected.

SOLUTION:
The vulnerability has been fixed in the CVS repositories by
supporting other serialization protocols and further restricting the
set of classes that are accepted for de-serialization.

Play network games only when connected to trusted networks.
