Mandriva Linux Security Advisory MDVSA-2013:054
http://www.mandriva.com/en/support/security/
_______________________________________________________________________

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

Problem Description:

Multiple vulnerabilities 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).

sudo 1.6.0 through 1.7.10p6 and sudo 1.8.0 through 1.8.6p6 allows
local users or physically-proximate attackers to bypass intended time
restrictions and retain privileges without re-authenticating by setting
the system clock and sudo user timestamp to the epoch (CVE-2013-1775).

Sudo before 1.8.6p7 allows a malicious user to run commands via
sudo without authenticating, so long as there exists a terminal the
user has access to where a sudo command was successfully run by that
same user within the password timeout period (usually five minutes)
(CVE-2013-1776).

The updated packages have been patched to correct these issues.
