• Status: RESOLVED FIXED
• Product: Gentoo Security

[Description Stefan Behte (RETIRED) 2010-06-25 19:54:41 UTC]

CVE-2010-1436 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-1436):
  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.
