Description Marcel Holtmann 2006-11-23 06:06:18 UTC
From MOKB-14-11-2006:

http://projects.info-pull.com/mokb/MOKB-14-11-2006.html

Failure to handle mounting of corrupt filesystem streams may lead to a local
denial of service condition when SELinux hooks are enabled. This particular
vulnerability is caused by a null pointer dereference in the superblock_doinit
function.

Comment 1 Eric Paris 2006-11-30 15:34:12 UTC
Not an SELinux problem.  It's a problem in HFS return codes from failure. 
Already fixed upstream by Eric Sandeen.  Will discuss which of us should own the
local bug (we both know the fix just fine)

Comment 3 Jason Baron 2006-12-13 19:19:12 UTC
committed in stream U5 build 42.31. A test kernel with this patch is available
from http://people.redhat.com/~jbaron/rhel4/


Comment 4 Jason Baron 2006-12-18 21:54:44 UTC
committed in stream E5 build 42.0.4

Comment 6 Mike Gahagan 2007-01-19 19:08:47 UTC
verified using the MOKB hfs image.
