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. _______________________________________________________________________
