Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
An untrusted search path vulnerability in python-updater might result |
| 19 |
in the execution of arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
python-updater is a script used to remerge python packages when |
| 25 |
changing Python version. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |
| 29 |
|
| 30 |
------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 app-admin/python-updater < 0.7-r1 >= 0.7-r1 |
| 34 |
|
| 35 |
Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Robert Buchholz of the Gentoo Security Team reported that |
| 39 |
python-updater includes the current working directory and |
| 40 |
subdirectories in the Python module search path (sys.path) before |
| 41 |
calling "import". |
| 42 |
|
| 43 |
Impact |
| 44 |
====== |
| 45 |
|
| 46 |
A local attacker could entice the root user to run "python-updater" |
| 47 |
from a directory containing a specially crafted Python module, |
| 48 |
resulting in the execution of arbitrary code with root privileges. |
| 49 |
|
| 50 |
Workaround |
| 51 |
========== |
| 52 |
|
| 53 |
Do not run "python-updater" from untrusted working directories. |
| 54 |
|
| 55 |
Resolution |
| 56 |
========== |
| 57 |
|
| 58 |
All python-updater users should upgrade to the latest version: |
| 59 |
|
| 60 |
# emerge --sync |
| 61 |
# emerge --ask --oneshot --verbose ">=app-admin/python-updater-0.7-r1" |
| 62 |
