CVE-2011-1089 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-1089):
  The addmntent function in the GNU C Library (aka glibc or libc6) 2.13 and
  earlier does not report an error status for failed attempts to write to the
  /etc/mtab file, which makes it easier for local users to trigger corruption
  of this file, as demonstrated by writes from a process with a small
  RLIMIT_FSIZE value, a different vulnerability than CVE-2010-0296.


Maintainers, please provide an updated ebuild, targeted for stabilization. Thanks.
