CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:L/AC:M/Au:N/C:C/I:C/A:C

Summary:
The remote host is missing an update for the 'sudo' Linux Distribution Package(s) announced via the referenced advisory.

Affected Versions:
sudo on Mandriva Linux 2009.0, Mandriva Linux 2009.0/X86_64, Mandriva Linux 2010.0, Mandriva Linux 2010.0/X86_64, Mandriva Linux 2010.1, Mandriva Linux 2010.1/X86_64, Mandriva Enterprise Server 5, Mandriva Enterprise Server 5/X86_64

Technical Details:
Multiple vulnerabilities has been found and corrected in sudo: A a patch for parse.c in sudo does not properly interpret a system group (aka %group) in the sudoers file during authorization decisions for a user who belongs to that group, which allows local users to leverage an applicable sudoers file and gain root privileges via a sudo command. NOTE: this vulnerability exists because of a CVE-2009-0034 regression (CVE-2011-0008). check.c in sudo 1.7.x before 1.7.4p5, when a Runas group is configured, does not require a password for command execution that involves a gid change but no uid change, which allows local users to bypass an intended authentication requirement via the -g option to a sudo command (CVE-2011-0010). Packages for 2009.0 are provided as of the Extended Maintenance Program. The updated Linux Distribution Packages have been upgraded to the latest versions (1.7.4p6) which is not affected by these issues.

Recommendations:
Please Install the Updated Packages.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
