"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:

The updated packages have been upgraded to the latest versions
