  "description": "Network Security Services (NSS) is a set of libraries designed to support the cross-platform development of security-enabled client and server applications.\n\nNetscape Portable Runtime (NSPR) provides platform independence for non-GUI operating system facilities.\n\nThe following packages have been upgraded to a later upstream version: nss (3.53.1), nspr (4.25.0). (BZ#1809549, BZ#1809550)\n\nSecurity Fix(es):\n\n* nss: UAF in sftk_FreeSession due to improper refcounting (CVE-2019-11756)\n\n* nss: Check length of inputs for cryptographic primitives (CVE-2019-17006)\n\n* nss: Side channel vulnerabilities during RSA key generation (CVE-2020-12402)\n\n* nss: TLS 1.3 HelloRetryRequest downgrade request sets client into invalid state (CVE-2019-17023)\n\nFor 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.\n\nBug Fix(es):\n\n* Install of update of nss.x86_64 adds i686 into transaction (BZ#1663187)\n\n* NSS does not set downgrade sentinel in ServerHello.random for TLS 1.0 and TLS 1.1 (BZ#1691409)\n\n* TLS Keying Material Exporter is unsupported by command line tools (BZ#1691454)\n\n* TLS_AES_256_GCM_SHA384 is not marked as FIPS compatible (BZ#1711375)\n\n* Make TLS 1.3 work in FIPS mode (BZ#1724250)\n\n* NSS rejects records with large padding with SHA384 HMAC (BZ#1750921)\n\n* NSS missing IKEv1 Quick Mode KDF (BZ#1809637)\n\n* Name Constraints validation: CN treated as DNS name even when syntactically invalid as DNS name (BZ#1825270)\n\n* FIPS needs nss to restrict valid dh primes to those primes that are approved. (BZ#1854564)\n\n* nss needs to comply to the new SP800-56A rev 3 requirements (BZ#1855825)\n\nEnhancement(s):\n\n* [RFE] nss should use AES for storage of keys (BZ#1723819)",
