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:
  libnss3                         2:3.35-2ubuntu2.2

Ubuntu 16.04 LTS:
  libnss3                         2:3.28.4-0ubuntu0.16.04.5

Ubuntu 14.04 LTS:
  libnss3                         2:3.28.4-0ubuntu0.14.04.5

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