Ubuntu update for quagga

Typically used for cross-site scripting vulnerabilities and privilege escalation vulnerabilities.

This rating is also used for vulnerabilities allowing exposure of sensitive data to local users.

"From local network" describes vulnerabilities where the attack vector requires that an attacker is situated on the same network as a vulnerable system (not necessarily a LAN).

This category covers vulnerabilities in certain services (e.g. DHCP, RPC, administrative services) that should not be accessible from the Internet, but only from a local network and optionally a restricted set of external systems.
