Detail

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:
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.
