Several security issues were fixed in NSS.

It was discovered that NSS incorrectly handled certain invalid
Diffie-Hellman keys. A remote attacker could possibly use this flaw to
cause NSS to crash, resulting in a denial of service. This issue only
applied to Ubuntu 12.04 LTS, Ubuntu 14.04 LTS and Ubuntu 16.04 LTS.
(CVE-2016-5285)

Hubert Kario discovered that NSS incorrectly handled Diffie Hellman client
key exchanges. A remote attacker could possibly use this flaw to perform a
small subgroup confinement attack and recover private keys. This issue only
applied to Ubuntu 12.04 LTS, Ubuntu 14.04 LTS and Ubuntu 16.04 LTS.
(CVE-2016-8635)

Franziskus Kiefer discovered that NSS incorrectly mitigated certain timing
side-channel attacks. A remote attacker could possibly use this flaw to
