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

====================================================================
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.
