"USN-810-1 fixed vulnerabilities in NSS. This update provides the NSPR
needed to use the new NSS.

Moxie Marlinspike discovered that NSS did not properly handle regular
expressions in certificate names. A remote attacker could create a
specially crafted certificate to cause a denial of service (via
application crash) or execute arbitrary code as the user invoking the
program. (CVE-2009-2404)

Moxie Marlinspike and Dan Kaminsky independently discovered
that NSS did not properly handle certificates with NULL
characters in the certificate name. An attacker could
exploit this to perform a man in the middle attack to view
sensitive information or alter encrypted communications.
(CVE-2009-2408)

Dan Kaminsky discovered NSS would still accept certificates
with MD2 hash signatures. As a result, an attacker could
potentially create a malicious trusted certificate to
impersonate another site. (CVE-2009-2409).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
