Moderate: nss and nspr security, bug fix, and enhancement update

Network Security Services (NSS) is a set of libraries designed to support the cross-platform development of security-enabled client and server applications.

Netscape Portable Runtime (NSPR) provides platform independence for non-GUI operating system facilities.

The following packages have been upgraded to a later upstream version: nss (3.53.1), nspr (4.25.0). (BZ#1809549, BZ#1809550)

Security Fix(es):

* nss: UAF in sftk_FreeSession due to improper refcounting (CVE-2019-11756)

* nss: Check length of inputs for cryptographic primitives (CVE-2019-17006)

* nss: Side channel vulnerabilities during RSA key generation (CVE-2020-12402)

* nss: TLS 1.3 HelloRetryRequest downgrade request sets client into invalid state (CVE-2019-17023)

* NSS missing IKEv1 Quick Mode KDF (BZ#1809637)

* Name Constraints validation: CN treated as DNS name even when syntactically invalid as DNS name (BZ#1825270)

* FIPS needs nss to restrict valid dh primes to those primes that are approved. (BZ#1854564)

* nss needs to comply to the new SP800-56A rev 3 requirements (BZ#1855825)

Enhancement(s):

* [RFE] nss should use AES for storage of keys (BZ#1723819)
