 Mandriva Linux Security Advisory                         MDVSA-2012:079
 http://www.mandriva.com/security/
 _______________________________________________________________________

 Package : sudo
 Date    : May 21, 2012
 Affected: 2010.1, 2011., Enterprise Server 5.0
 _______________________________________________________________________

 Problem Description:

 A vulnerability has been found and corrected in sudo:
 
 A flaw exists in the IP network matching code in sudo versions 1.6.9p3
 through 1.8.4p4 that may result in the local host being matched
 even though it is not actually part of the network described by the
 IP address and associated netmask listed in the sudoers file or in
 LDAP. As a result, users authorized to run commands on certain IP
 networks may be able to run commands on hosts that belong to other
 networks not explicitly listed in sudoers (CVE-2012-2337
 
 The updated packages have been patched to correct this issue.
