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 sftkFreeSession 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) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.Bug Fix(es): Install of update of nss.x8664 adds i686 into transaction (BZ#1663187) NSS does not set downgrade sentinel in ServerHello.random for TLS 1.0 and TLS 1.1 (BZ#1691409) TLS Keying Material Exporter is unsupported by command line tools (BZ#1691454) TLSAES256GCMSHA384 is not marked as FIPS compatible (BZ#1711375) Make TLS 1.3 work in FIPS mode (BZ#1724250) NSS rejects records with large padding with SHA384 HMAC (BZ#1750921) 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)
