ID: 201001-07
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
=======
An untrusted search path vulnerability in Blender might result in the
execution of arbitrary code.
Background
=========
Blender is a 3D Creation/Animation/Publishing System.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-gfx/blender < 2.48a-r3 >= 2.48a-r3
Description
==========
Steffen Joeris reported that Blender's BPY_interface calls
PySys_SetArgv() in such a way that Python prepends sys.path with an
empty string.
Impact
=====
A local attacker could entice a user to run "blender" from a directory
containing a specially crafted Python module, resulting in the
execution of arbitrary code with the privileges of the user running the
application.
Workaround
=========
There is no known workaround at this time.
Resolution
=========
All Blender users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/blender-2.48a-r3"
References
