March 14, 2013

nspr update
============================================================================

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

- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 10.04 LTS

Summary:

NSPR update to work with the new NSS.

Software Description:
- nspr: NetScape Portable Runtime Library

Details:

USN-1763-1 fixed a vulnerability in NSS. This update provides the NSPR
needed to use the new NSS.

Original advisory details:

 Nadhem Alfardan and Kenny Paterson discovered that the TLS protocol as used
 in NSS was vulnerable to a timing side-channel attack known as the
 "Lucky Thirteen" issue. A remote attacker could use this issue to perform
 plaintext-recovery attacks via analysis of timing data.

Update instructions:

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

Ubuntu 12.10:
  libnspr4                        4.9.5-0ubuntu0.12.10.1

Ubuntu 12.04 LTS:
  libnspr4                        4.9.5-0ubuntu0.12.04.1

Ubuntu 11.10:
  libnspr4                        4.9.5-0ubuntu0.11.10.1

Ubuntu 10.04 LTS:
  libnspr4-0d                     4.9.5-0ubuntu0.10.04.1

After a standard system update you need to restart any applications that
use NSPR, such as Evolution and Chromium, to make all the necessary changes.
