Ubuntu 14.04 LTS : Unity vulnerabilities (USN-2184-2)

high Nessus Plugin ID 73799

Synopsis

The remote Ubuntu host is missing a security update.

Description

USN-2184-1 fixed lock screen vulnerabilities in Unity. Further testing has uncovered more issues which have been fixed in this update. This update also fixes a regression with the shutdown dialogue.

We apologize for the inconvenience.

Frederic Bardy discovered that Unity incorrectly filtered keyboard shortcuts when the screen was locked. A local attacker could possibly use this issue to run commands, and unlock the current session.

Giovanni Mellini discovered that Unity could display the Dash in certain conditions when the screen was locked. A local attacker could possibly use this issue to run commands, and unlock the current session.

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.

Solution

Update the affected packages.
