-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Moderate: nss and nspr security, bug fix, and enhancement update Advisory ID: RHSA-2020:3280-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2020:3280 Issue date: 2020-08-03 CVE Names: CVE-2019-11756 CVE-2019-17006 CVE-2019-17023 CVE-2020-12402 ==================================================================== 1. Summary: An update for nss and nspr is now available for Red Hat Enterprise Linux 8. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux AppStream (v. 8) - aarch64, ppc64le, s390x, x86_64 3. Description: 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) 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.x86_64 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) * TLS_AES_256_GCM_SHA384 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) 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 After installing this update, applications using NSS (for example, Firefox) must be restarted for this update to take effect. After installing this update, applications using NSPR (for example, Firefox) must be restarted for this update to take effect. 5. Bugs fixed (https://bugzilla.redhat.com/): 1663187 - Install of update of nss.x86_64 adds i686 into transaction 1691454 - TLS Keying Material Exporter is unsupported by command line tools 1711375 - TLS_AES_256_GCM_SHA384 is not marked as FIPS compatible 1724250 - Make TLS 1.3 work in FIPS mode [rhel-8] 1750921 - NSS rejects records with large padding with SHA384 HMAC 1774835 - CVE-2019-11756 nss: UAF in sftk_FreeSession due to improper refcounting 1775916 - CVE-2019-17006 nss: Check length of inputs for cryptographic primitives 1791225 - CVE-2019-17023 nss: TLS 1.3 HelloRetryRequest downgrade request sets client into invalid state 1809637 - NSS missing IKEv1 Quick Mode KDF 1825270 - Name Constraints validation: CN treated as DNS name even when syntactically invalid as DNS name 1826231 - CVE-2020-12402 nss: Side channel vulnerabilities during RSA key generation 1854564 - FIPS needs nss to restrict valid dh primes to those primes that are approved.
