## Description

gfs2 in the Linux kernel 2.6.18, and possibly other versions, does not
properly handle when the gfs2\_quota struct occupies two separate pages,
which allows local users to cause a denial of service (kernel panic) via
certain manipulations that cause an out-of-bounds write, as demonstrated by
writing from an ext3 file system to a gfs2 file system.

## Notes

### [smb](https://launchpad.net/~smb)

The upstream patch did not apply to anything and needed some backport.
I think I got the functionality right but review is welcome.
Dapper only has gfs(1) support and should therefor not be affected.
