CVE ID:	CVE-2005-4470
Description:	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.
Test IDs:	1.3.6.1.4.1.25623.1.1.12.2006.238.2   1.3.6.1.4.1.25623.1.0.56661   1.3.6.1.4.1.25623.1.0.56123   1.3.6.1.4.1.25623.1.0.56150
