========================

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

- Ubuntu 13.10
- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS

Summary:

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

Software Description:
- nspr: NetScape Portable Runtime Library

Details:

It was discovered that NSPR incorrectly handled certain malformed X.509
certificates. A remote attacker could use a crafted X.509 certificate to
cause NSPR to crash, leading to a denial of service, or possibly execute
arbitrary code.

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

Ubuntu 13.10:
