Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
A design error in Py2Play allows attackers to execute arbitrary code. |
| 19 |
|
| 20 |
Background |
| 21 |
========== |
| 22 |
|
| 23 |
Py2Play is a peer-to-peer network game engine written in Python. |
| 24 |
Pickling is a Python feature allowing to serialize Python objects into |
| 25 |
string representations (called pickles) that can be sent over the |
| 26 |
network. |
| 27 |
|
| 28 |
Affected packages |
| 29 |
================= |
| 30 |
|
| 31 |
------------------------------------------------------------------- |
| 32 |
Package / Vulnerable / Unaffected |
| 33 |
------------------------------------------------------------------- |
| 34 |
1 dev-python/py2play <= 0.1.7 Vulnerable! |
| 35 |
------------------------------------------------------------------- |
| 36 |
NOTE: Certain packages are still vulnerable. Users should migrate |
| 37 |
to another package if one is available or wait for the |
| 38 |
existing packages to be marked stable by their |
| 39 |
architecture maintainers. |
| 40 |
|
| 41 |
Description |
| 42 |
=========== |
| 43 |
|
| 44 |
Arc Riley discovered that Py2Play uses Python pickles to send objects |
| 45 |
over a peer-to-peer game network, and that clients accept without |
| 46 |
restriction the objects and code sent by peers. |
| 47 |
|
| 48 |
Impact |
| 49 |
====== |
| 50 |
|
| 51 |
A remote attacker participating in a Py2Play-powered game can send |
| 52 |
malicious Python pickles, resulting in the execution of arbitrary |
| 53 |
Python code on the targeted game client. |
| 54 |
|
| 55 |
Workaround |
| 56 |
========== |
| 57 |
|
| 58 |
There is no known workaround at this time. |
| 59 |
|
| 60 |
Resolution |
| 61 |
========== |
| 62 |
|
| 63 |
The Py2Play package has been hard-masked prior to complete removal from |
| 64 |
Portage, and current users are advised to unmerge the package: |
| 65 |
|
| 66 |
# emerge --unmerge dev-python/py2play |
| 67 |
|
| 68 |
