Heap-based buffer overflow in the get_bhead function in readfile.c in Blender BlenLoader 2.0 through 2.40pre allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a .blend file with a negative bhead.len value, which causes less memory to be allocated than expected, possibly due to an integer overflow.

CVE-2005-4470 Blender vulnerability
Title: Blender vulnerability
Summary: Blender vulnerability
Damian Put discovered that Blender did not properly validate a
'length' value in .blend files. Negative values led to an
insufficiently sized memory allocation. By tricking a user into
opening a specially crafted .blend file, this could be exploited to
execute arbitrary code with the privileges of the Blender user.
Instructions: In general, a standard system update will make all the necessary changes.
