| Severity: | normal |
| Title: | Blender: Untrusted search path |
| Date: | 01/13/2010 |
| Bugs: | |
| 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 | Architecture(s) |
|---|---|---|---|
| media-gfx/blender | < 2.48a-r3 | >= 2.48a-r3 | All supported architectures |
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"
