decoding certain ASN.1 data. An remote attacker could use this issue to
cause NSS to crash, resulting in a denial of service, or possibly execute
arbitrary code.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 15.10
Ubuntu 15.04
Ubuntu 14.04
Ubuntu 12.04

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