Description Jan Lieskovsky 2012-05-10 16:32:11 UTC
A security flaw was found in the way sudo granted access for particular host, when multiple netmask values have been used in sudo's Host / Host_List configuration. Such configuration allowed unprivileged users, who were authorized by the sudoers file to run their sudo commands, to run these commands from any host regardless of the Host_List configuration (even from hosts, which were intended according to the Host_List netmask configuration not to allow execution of such commands according to the netmask).
