 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.
