Summary
nss vulnerabilities
Details

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 recover private keys. (CVE-2016-9074)

This update refreshes the NSS package to version 3.26.2 which includes the latest CA certificate bundle.
