Description Mark J. Cox 2005-10-17 06:07:39 EDT
The CVE description of this issue is "The HFS and HFS+ (hfsplus) modules in
Linux 2.6 allows attackers to cause a denial of service (oops) by using hfsplus
to mount a filesystem that is not hfsplus."  

However this is actually two issues as can be seen from the commit:

The first is that in certain error cases for hfs and hfsplus there is a failure
to free kernel structure.   The second is a hfsplus flaw that could lead to a crash.

There turns out be a memory leak in the hfsplus failure path as well, so I
fixed that too.

The changes for all of these fixes mimic those from upstream.
