Description:   Opened: 2006-01-07 05:00 0000 
Stumbled upon the Ubuntu advisory, so we're a bit late.

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.

I keep getting 

./usr/share/doc/
./usr/share/doc/blender-2.40/
./usr/share/doc/blender-2.40/COPYING.gz
./usr/share/doc/blender-2.40/INSTALL.gz
./usr/share/doc/blender-2.40/README.gz
>>> Done.
!!! CATEGORY info missing from info chunk, aborting...

here, even after deleting the binpkg generated from FEATURES=buildpkg.. maybe
someone else from amd64 can test this? I doubt it is related to blender

------- Comment #6 From Simon Stelling (RETIRED) 2006-01-10 11:08:52 0000 ------- 
hparker confirmed that it works, so amd64 stable
