==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
– Ubuntu 18.10
– Ubuntu 18.04 LTS
– Ubuntu 16.04 LTS
– Ubuntu 14.04 LTS
Summary:
NSS could be made to crash if it received specially crafted network
traffic.
Software Description:
– nss: Network Security Service library
Details:
Hanno Böck and Damian Poddebniak discovered that NSS incorrectly handled
certain CMS functions. A remote attacker could possibly use this issue to
cause NSS to crash, resulting in a denial of service.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 18.10:
libnss3 2:3.36.1-1ubuntu1.2
Ubuntu 18.04 LTS:

Ubuntu 14.04 LTS:

After a standard system update you need to restart any applications that
use NSS, such as Evolution, to make all the necessary changes.
