From secunia security advisory at $URL:

Description:
The vulnerability is caused due to a boundary error within the "xfs_readlink()" function (fs/xfs/xfs_vnodeops.c) and can be exploited to cause a buffer overflow via a specially crafted XFS image.


Solution:
unpatched atm.

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.
Comment 2 Christopher Díaz Riveros (RETIRED) gentoo-dev Security 2018-04-04 19:48:13 UTC 
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.
