Description Stefan Behte (RETIRED) gentoo-dev Security 2009-02-27 22:26:34 UTC
CVE-2009-0747 (
  The ext4_isize function in fs/ext4/ext4.h in the Linux kernel 2.6.27
  before and 2.6.28 before uses the i_size_high
  structure member during operations on arbitrary types of files, which
  allows local users to cause a denial of service (CPU consumption and
  error-message flood) by attempting to mount a crafted ext4 filesystem.
