Description:
 The Linux kernel 2.6.x up to 2.6.18, and possibly other versions, on
 Fedora Core 6 and possibly other operating systems, allows local
 users to cause a denial of service (crash) via a malformed gfs2 file
 stream that triggers a NULL pointer dereference in the init_journal
 function.
Ubuntu-Description: 
Notes: 
 <fabbione> yes we do but it's not usable
 <pitti> that means you cannot create a gfs2 fs?
 <fabbione> it's marked as experimental
 <fabbione> you can
 <fabbione> but there is no way it will last working for more than 10 seconds on load
 <fabbione> it's totally buggy at design level
 <fabbione> even what's in linus tree is broken
 <pitti> ok, so we can treat this with low priority

 gfs2 should just be disabled in edgy-security.

 <dannf> etch's 2.6.18 didn't include gfs
