USN-810-1 fixed vulnerabilities in NSS. This update provides the NSPR
needed to use the new NSS.
Original advisory details:
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 machine-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)
