Alexander Kurtz discovered that sudo would not prompt for a password when
a group was specified in the Runas_Spec. A local attacker could exploit

Runas_Spec is not used in the default installation of Ubuntu.
The problem can be corrected by updating your system to the following package versions:
In general, a standard system update will make all the necessary changes.
