Description

It was discovered that Vino incorrectly transmitted clipboard activity before authenticating the remote connection. A remote attacker could connect to Vino and monitor clipboard activity.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
