Severity: High Title: Py2Play: Remote execution of arbitrary Python code Date: September 17, 2005 Bugs: #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 / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-python/py2play <= 0.1.7 Vulnerable! ------------------------------------------------------------------- NOTE: Certain packages are still vulnerable. Users should migrate to another package if one is available or wait for the existing packages to be marked stable by their architecture maintainers.
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 ==========
The Py2Play package has been hard-masked prior to complete removal from Portage, and current users are advised to unmerge the package:
# emerge --unmerge dev-python/py2play
