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 References ========== [ 1 ] CAN-2005-2875 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-2875 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200509-09.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
