CVE-2005-4470  (opens in a new tab)

How to fix?

Upgrade Echo:latest blender to version 2.40-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream blender package and not the blender package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

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.
