Network Security Services is a set of libraries designed to support the cross-platform development of security-enabled client and server applications. Netscape Portable Runtime provides platform independence for non-GUI operating system facilities. The following packages have been upgraded to a later upstream version: nss , nspr . Security Fix: * nss: UAF in sftk_FreeSession due to improper refcounting * nss: Check length of inputs for cryptographic primitives * nss: Side channel vulnerabilities during RSA key generation * nss: TLS 1.3 HelloRetryRequest downgrade request sets client into invalid state For more details about the security issue, including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page listed in the References section. Bug Fix: * Install of update of nss.x86_64 adds i686 into transaction * NSS does not set downgrade sentinel in ServerHello.random for TLS 1.0 and TLS 1.1 * TLS Keying Material Exporter is unsupported by command line tools * TLS_AES_256_GCM_SHA384 is not marked as FIPS compatible * Make TLS 1.3 work in FIPS mode * NSS rejects records with large padding with SHA384 HMAC * NSS missing IKEv1 Quick Mode KDF * Name Constraints validation: CN treated as DNS name even when syntactically invalid as DNS name * FIPS needs nss to restrict valid dh primes to those primes that are approved. * nss needs to comply to the new SP800-56A rev 3 requirements Enhancement: * [RFE] nss should use AES for storage of keys
