• Ubuntu 16.04 ESM
• Ubuntu 14.04 ESM

Packages

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

• libnss3 - 2:3.35-2ubuntu2.2

• libnss3 - 2:3.28.4-0ubuntu0.16.04.5

Ubuntu 14.04

• 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.
