Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:3280 advisory.

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)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
