===================================================================== Red Hat Security Advisory
Synopsis: Moderate: nss security and bug fix update Advisory ID: RHSA-2021:0538-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2021:0538 Issue date: 2021-02-16 CVE Names: CVE-2020-6829 CVE-2020-12400 CVE-2020-12403 =====================================================================
1. Summary:
An update for nss 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.
Security Fix(es):
* nss: Side channel attack on ECDSA signature generation (CVE-2020-6829)
* nss: P-384 and P-521 implementation uses a side-channel vulnerable modular inversion function (CVE-2020-12400)
* nss: CHACHA20-POLY1305 decryption with undersized tag leads to out-of-bounds read (CVE-2020-12403)
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):
* Support key wrap/unwrap with RSA-OAEP (BZ#1896431)
* 1536bit group from RFC3526 is allowed in FIPS mode when in policy DH-MIN is set to be lower than 1536 (BZ#1896432)
* when NSS_SDB_USE_CACHE not set, after curl access https, dentry increase but never released - consider alternative algorithm for benchmarking ACCESS call in sdb_measureAccess [rhel-8] (BZ#1896933)
* Policy should allow overriding library defaults (BZ#1898702)
* KDF-self-tests-induced changes for nss in RHEL 8.4 (BZ#1898953)
* nss: non-blocksize requests to IKEv1 KDF returns bogus output (BZ#1904408)
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
