medium Nessus Plugin ID 51809
Language:
Synopsis
The remote Mandriva Linux host is missing a security update.Description
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. Please visit this link to learn more:
