Mandriva Linux Security Advisory MDVSA-2013:048
http://www.mandriva.com/en/support/security/
_______________________________________________________________________

Package : ncpfs
Date : April 5, 2013
Affected: Business Server 1.0
_______________________________________________________________________

Problem Description:

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.
