 Mandriva Linux Security Advisory                         MDVSA-2011:018
 http://www.mandriva.com/security/
 _______________________________________________________________________

 Package : sudo
 Date    : January 21, 2011
 Affected: 2009.0, 2010.0, 2010.1, Enterprise Server 5.0
 _______________________________________________________________________

 Problem 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:
 http://store.mandriva.com/product_info.php?cPath=149&amp;products_id=490
 
 The updated packages have been upgraded to the latest versions
 (1.7.4p6) which is not affected by these issues.
