Description Stefan Behte (RETIRED) gentoo-dev Security 2009-02-27 22:20:11 UTC 
CVE-2009-0746 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-0746):
  The make_indexed_dir function in fs/ext4/namei.c in the Linux kernel
  2.6.27 before 2.6.27.19 and 2.6.28 before 2.6.28.7 does not validate
  a certain rec_len field, which allows local users to cause a denial
  of service (OOPS) by attempting to mount a crafted ext4 filesystem.
