Fraudulent security certificates could allow sensitive information to be exposed when accessing the Internet.

Summary

Fraudulent security certificates could allow sensitive information to

be exposed when accessing the Internet.

Software Description:

- nss: Network Security Service library

Details:

Two intermediate CA certificates were mis-issued by the TURKTRUST

certificate authority. If a remote attacker were able to perform a

man-in-the-middle attack, this flaw could be exploited to view sensitive

information.

Update Instructions

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

Ubuntu 12.10:
  libnss3-1d                      3.14.1-0ckbi1.93ubuntu.0.12.10.1

Ubuntu 12.04 LTS:
  libnss3-1d                      3.14.1-0ckbi1.93ubuntu.0.12.04.1

Ubuntu 11.10:
  libnss3-1d                      3.14.1-0ckbi1.93ubuntu.0.11.10.1

Ubuntu 10.04 LTS:
  libnss3-1d                      3.14.1-0ckbi1.93ubuntu.0.10.04.1

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.
