Description Robert Buchholz (RETIRED) gentoo-dev 2008-08-15 12:47:43 UTC
CVE-2008-3534 (
  The shmem_delete_inode function in mm/shmem.c in the tmpfs implementation in
  the Linux kernel before allows local users to cause a denial of
  service (system crash) via a certain sequence of file create, remove, and
  overwrite operations, as demonstrated by the insserv program, related to
  allocation of "useless pages" and improper maintenance of the i_blocks count.

Fixed in and
Comment 2 into-the-trash-it-goes 2009-07-20 22:46:49 UTC
Beware, the patch introduced an independent bug which was subsequently fixed in and respectively:

"fbdefio: add set_page_dirty handler to deferred IO FB";a=commitdiff;h=d847471d063663b9f36927d265c66a270c0cfaab

Anyhow, hardened-kernel unaffected at present time. Removing alias.
