========================================================================== Ubuntu Security Notice USN-3336-1 June 21, 2017
nss vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 17.04 - Ubuntu 16.10 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS
Summary:
NSS could be made to crash if it received specially crafted network traffic.
Software Description: - nss: Network Security Service library
Details:
It was discovered that NSS incorrectly handled certain empty SSLv2 messages. 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 17.04: libnss3 2:3.28.4-0ubuntu0.17.04.2
Ubuntu 16.10: libnss3 2:3.28.4-0ubuntu0.16.10.2
Ubuntu 16.04 LTS: libnss3 2:3.28.4-0ubuntu0.16.04.2
Ubuntu 14.04 LTS: libnss3 2:3.28.4-0ubuntu0.14.04.2
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.
