RHSA-2020:3280 - Moderate: nss and nspr security, bug fix, and enhancement update

Synopsis

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

Type/Severity

Security Advisory Moderate

Topic

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.

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)

Solution

For details on how to apply this update, which includes the changes described in this advisory, refer to:
