20
21 Background
22 ==========
23
24 Blender is an open source software for 3D modeling, animation,
25 rendering, post-production, interactive creation and playback.

35 Description
36 ===========
37
38 Damian Put has reported a flaw due to an integer overflow in the
39 "get_bhead()" function, leading to a heap overflow when processing
40 malformed ".blend" files.
41
42 Impact
43 ======
44
45 A remote attacker could entice a user into opening a specially crafted
46 ".blend" file, resulting in the execution of arbitrary code with the
47 permissions of the user running Blender.

49 Workaround
50 ==========
51
52 There is no known workaround at this time.
53
54 Resolution
55 ==========

59 # emerge --sync
60 # emerge --ask --oneshot --verbose ">=media-gfx/blender-2.40"
