Description Robert Buchholz (RETIRED) gentoo-dev 2008-08-15 10:56:24 UTC
CVE-2008-3275 (
  The (1) real_lookup and (2) __lookup_hash functions in fs/namei.c in the vfs
  implementation in the Linux kernel before does not prevent creation
  of a child dentry for a deleted (aka S_DEAD) directory, which allows local
  users to cause a denial of service ("overflow" of the UBIFS orphan area) via
  a series of attempted file creations within deleted directories.
