CVE-2005-3109 HFS oops
Last modified: 2007-11-30 17:07:21 EST
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.
Created attachment 120823 [details]
Created attachment 120827 [details]
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.
commited in -22.23
