CVE-2009-4308 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-4308):
  The ext4_decode_error function in fs/ext4/super.c in the ext4
  filesystem in the Linux kernel before 2.6.32 allows user-assisted
  remote attackers to cause a denial of service (NULL pointer
  dereference), and possibly have unspecified other impact, via a
  crafted read-only filesystem that lacks a journal.
