Description Stefan Behte (RETIRED) gentoo-dev Security 2010-09-03 20:52:30 UTC
CVE-2010-0296 (
  The encode_name macro in misc/mntent_r.c in the GNU C Library (aka
  glibc or libc6) 2.11.1 and earlier, as used by ncpmount and
  mount.cifs, does not properly handle newline characters in mountpoint
  names, which allows local users to cause a denial of service (mtab
  corruption), or possibly modify mount options and gain privileges,
  via a crafted mount request.

Please advice if it's already patched, you always seem to know this anyways... ;)
Comment 2 SpanKY gentoo-dev 2010-09-03 21:08:11 UTC
the fix is already in glibc-2.11.2 which is stable for most everyone ... maybe only hppa/s390 still need keywording
