Mandriva Linux Security Advisory MDVSA-2013:026
http://www.mandriva.com/en/support/security/
_______________________________________________________________________

Package : sudo
Date : March 18, 2013
Affected: Enterprise Server 5.0
_______________________________________________________________________

Problem Description:

Multiple vulnerabilities has been found and corrected in sudo:

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.
