Blender is an open source software for 3D modeling, animation, rendering, post-production, interactive creation and playback.
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.
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.
There is no known workaround at this time.
All Blender users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/blender-2.40"
