Synopsis
========
An untrusted search path vulnerability in python-updater might result
in the execution of arbitrary code.

Background
==========
python-updater is a script used to remerge python packages when
changing Python version.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-admin/python-updater < 0.7-r1 >= 0.7-r1

Description
===========
Robert Buchholz of the Gentoo Security Team reported that
python-updater includes the current working directory and
subdirectories in the Python module search path (sys.path) before
calling "import".

Impact
======
A local attacker could entice the root user to run "python-updater"
from a directory containing a specially crafted Python module,
resulting in the execution of arbitrary code with root privileges.

Workaround
==========
Do not run "python-updater" from untrusted working directories.

Resolution
==========
All python-updater users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=app-admin/python-updater-0.7-=r1"

Availability
============
This GLSA and any updates to it are available for viewing at
the Gentoo Security Website:
