Synopsis
========
Blender is vulnerable to a buffer overflow that may be exploited by
attackers to execute arbitrary code.
Background
==========
Blender is an open source software for 3D modeling, animation,
rendering, post-production, interactive creation and playback.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-gfx/blender < 2.40 >= 2.40
Description
===========
Damian Put has reported a flaw due to an integer overflow in the
"get_bhead()" function, leading to a heap overflow when processing
malformed ".blend" files.
Impact
======
A remote attacker could entice a user into opening a specially crafted
".blend" file, resulting in the execution of arbitrary code with the
permissions of the user running Blender.
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-2.40"
References
