Ubuntu update for php

Typically used for remotely exploitable vulnerabilities that can lead to system compromise. Successful exploitation does not normally require any interaction but there are no known exploits available at the time of disclosure.

Such vulnerabilities can exist in services like FTP, HTTP, and SMTP or in client systems like email programs or browsers.

"From remote" describes other vulnerabilities where the attack vector doesn't require access to the system or a local network.

This category covers services that are acceptable to expose to the Internet (e.g. HTTP, HTTPS, SMTP). It also covers client applications used on the Internet and certain vulnerabilities where it is reasonable to assume that a security conscious user can be tricked into performing certain actions.
