CVE-2011-4077 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-4077):
  Buffer overflow in the xfs_readlink function in fs/xfs/xfs_vnodeops.c in XFS
  in the Linux kernel 2.6, when CONFIG_XFS_DEBUG is disabled, allows local
  users to cause a denial of service (memory corruption and crash) and
  possibly execute arbitrary code via an XFS image containing a symbolic link
  with a long pathname.

There are no longer any 2.x or kernels available in the repository with
the exception of sys-kernel/xbox-sources which is unsupported by security.
