Releases

Packages

  • 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
Ubuntu 18.04
Ubuntu 16.04
Ubuntu 14.04

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