CVE-2010-1436

Published: 21 May 2010

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

AuthorNote
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.

Priority

Low
