"Multiple vulnerabilities has been discovered and corrected in ncpfs :

ncpfs 2.2.6 and earlier attempts to use (1) ncpmount to append to the
/etc/mtab file and (2) ncpumount to append to the /etc/mtab.tmp file
without first checking whether resource limits would interfere, which
allows local users to trigger corruption of the /etc/mtab file via a
process with a small RLIMIT_FSIZE value, a related issue to
CVE-2011-1089 (CVE-2011-1679).

ncpmount in ncpfs 2.2.6 and earlier does not remove the /etc/mtab~
lock file after a failed attempt to add a mount entry, which has
unspecified impact and local attack vectors (CVE-2011-1680).

The updated packages have been patched to correct these issues."
