========================================================================== Ubuntu Security Notice USN-3163-1 January 04, 2017
nss vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.10 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS
Summary:
Several security issues were fixed in NSS.
Software Description: - nss: Network Security Service library
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.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.10: libnss3 2:3.26.2-0ubuntu0.16.10.1
Ubuntu 16.04 LTS: libnss3 2:3.26.2-0ubuntu0.16.04.2
Ubuntu 14.04 LTS: libnss3 2:3.26.2-0ubuntu0.14.04.3
Ubuntu 12.04 LTS: libnss3 2:3.26.2-0ubuntu0.12.04.1
This update uses a new upstream release, which includes additional bug fixes. 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.
