nspr vulnerability
==========================================================================

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

- Ubuntu 14.04 LTS
- Ubuntu 13.10
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS

Summary:

NSPR could be made to crash or run programs if it received specially
crafted input.

Software Description:
- nspr: NetScape Portable Runtime Library

Details:

Abhishek Arya discovered that NSPR incorrectly handled certain console
functions. A remote attacker could use this issue to cause NSPR to crash,
resulting in a denial of service, or possibly execute arbitrary code. The
default compiler options for affected releases should reduce the
vulnerability to a denial of service.

Update instructions:

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

Ubuntu 14.04 LTS:
  libnspr4                        2:4.10.2-1ubuntu1.1

Ubuntu 13.10:
  libnspr4                        2:4.9.5-1ubuntu1.2

Ubuntu 12.04 LTS:
  libnspr4                        4.9.5-0ubuntu0.12.04.3

Ubuntu 10.04 LTS:
  libnspr4-0d                     4.9.5-0ubuntu0.10.04.3

After a standard system update you need to restart your session to make all
the necessary changes.
