Releases

Packages

  • 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
Ubuntu 16.10
Ubuntu 16.04
Ubuntu 14.04

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.
