18 November 2013

nss vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 13.10
  • Ubuntu 13.04
  • Ubuntu 12.10
  • Ubuntu 12.04 LTS
  • Ubuntu 10.04 LTS


Several security issues were fixed in NSS.

Software Description

  • nss - Network Security Service library


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.
