Gentoo Linux Security Advisory

Title: Py2Play: Remote execution of arbitrary Python code (GLSA 200509-09)
Severity: high
Exploitable: remote
Date: September 17, 2005
Updated: September 05, 2006
Bug(s): #103524
ID: 200509-09

Synopsis


A design error in Py2Play allows attackers to execute arbitrary code.


Background


Py2Play is a peer-to-peer network game engine written in Python.
Pickling is a Python feature allowing to serialize Python objects into
string representations (called pickles) that can be sent over the
network.


Affected Packages

Package: dev-python/py2play
Vulnerable: <= 0.1.7
Unaffected: >= 0.1.8
Architectures: All supported architectures


Description


Arc Riley discovered that Py2Play uses Python pickles to send objects
over a peer-to-peer game network, and that clients accept without
restriction the objects and code sent by peers.


Impact


A remote attacker participating in a Py2Play-powered game can send
malicious Python pickles, resulting in the execution of arbitrary
Python code on the targeted game client.


Workaround


There is no known workaround at this time.


Resolution


All py2play users should upgrade to the latest version:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-python/py2play-0.1.8"
