CVE-2010-1436

Publication date 21 May 2010

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

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

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.
