CVE-2005-4470

https://notcve.org/view.php?id=CVE-2005-4470

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. • http://secunia.com/advisories/18176 http://secunia.com/advisories/18178 http://secunia.com/advisories/18452 http://secunia.com/advisories/19754 http://www.debian.org/security/2006/dsa-1039 http://www.gentoo.org/security/en/glsa/glsa-200601-08.xml http://www.overflow.pl/adv/blenderinteger.txt http://www.securityfocus.com/archive/1/419907/100/0/threaded http://www.securityfocus.com/bid/15981 http://www.vupen.com/english/advisories/2005/3032 https://usn.ubuntu.com •
