May 27, 2019

gnome-desktop3 vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 19.04
- Ubuntu 18.10
- Ubuntu 18.04 LTS


gnome-desktop could be made to escape the thumbnailer sandbox.

Software Description:
- gnome-desktop3: Introspection data for GnomeDesktop


It was discovered that gnome-desktop incorrectly confined thumbnailers. If
a user were tricked into downloading a malicious image file, a remote
attacker could possibly combine this issue with another vulnerability to
escape the sandbox and execute arbitrary code.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 19.04:
  libgnome-desktop-3-17           3.32.1-1ubuntu1.1

Ubuntu 18.10:
  libgnome-desktop-3-17           3.30.1-1ubuntu1.1

Ubuntu 18.04 LTS:
  libgnome-desktop-3-17           3.28.2-0ubuntu1.3

After a standard system update you need to restart your session to make all
the necessary changes.
