Description Marcel Holtmann 2006-11-23 08:23:04 UTC 
From MOKB-12-11-2006:

http://projects.info-pull.com/mokb/MOKB-12-11-2006.html

The ext2 filesystem code fails to properly handle corrupted data structures,
leading to an exploitable denial of service issue when read operation is being
done on a crafted fs stream.
Comment 1 Don Howard 2006-11-28 21:09:09 UTC 
While this does cause a noticable slowdown, the system is still accessable and
usable.  I don't think this rises to the level of a security issue.
Comment 3 Don Howard 2007-07-07 06:36:21 UTC 
A patch addressing this issue has been included in kernel-2.4.18-e.65.
