Insight
It was discovered that sudo incorrectly handled network masks when using Host and Host_List. A local user who is listed in sudoers may be allowed to run commands on unintended hosts when IPv4 network masks are used to grant access.
A local attacker could exploit this to bypass intended access restrictions. Host and Host_List are not used in the default installation of Ubuntu.
