Releases

Packages

  • nss - Network Security Service library

Details

Multiple security issues were discovered in NSS. If a user were tricked
into connecting to a malicious server, an attacker could possibly exploit
these to cause a denial of service via application crash, potentially
execute arbitrary code, or lead to information disclosure.

This update also adds TLS v1.2 support to Ubuntu 10.04 LTS, Ubuntu 12.04
LTS, Ubuntu 12.10, and Ubuntu 13.04.

Update instructions

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.

The problem can be corrected by updating your system to the following package versions:
