CVE-2009-0745 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-0745):
  The ext4_group_add function in fs/ext4/resize.c in the Linux kernel
  2.6.27 before 2.6.27.19 and 2.6.28 before 2.6.28.7 does not properly
  initialize the group descriptor during a resize (aka resize2fs)
  operation, which might allow local users to cause a denial of service
  (OOPS) by arranging for crafted values to be present in available
  memory.
