Description Stefan Behte (RETIRED) gentoo-dev Security 2009-01-26 21:11:46 UTC
CVE-2009-0269 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-0269):
  fs/ecryptfs/inode.c in the eCryptfs subsystem in the Linux kernel
  before 2.6.28.1 allows local users to cause a denial of service
  (fault or memory corruption), or possibly have unspecified other
  impact, via a readlink call that results in an error, leading to use
  of a -1 return value as an array index.

hardened-kernel unaffected at present time. Removing alias.

PS: Anything using >=genpatches-2.6.27-10 is unaffected (with the sole exception of genpatches-2.6.28-1
Comment 2 kfm 2009-07-21 03:18:19 UTC
I thought hardened had already taken care of this one with regard to the older kernel versions but apparently not. Adding back hardened-kernel; apologies for the noise.

Note: this issue is not addressed in any stable patch or genpatches release for either 2.6.25 or 2.6.26. However, the patch does apply.
