nss-3.53.1-17.0.1.el8

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

* 1536bit group from RFC3526 is allowed in FIPS mode when in policy DH-MIN is set to be lower than 1536

* 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

* Policy should allow overriding library defaults

* KDF-self-tests-induced changes for nss

* nss: non-blocksize requests to IKEv1 KDF returns bogus output

CVE-2020-12400
When converting coordinates from projective to affine, the modular inversion was not performed in constant time, resulting in a possible timing-based side channel attack. This vulnerability affects Firefox < 80 and Firefox for Android < 80.
CVE-2020-12403
** RESERVED ** This candidate has been reserved by an organization or individual that will use it when announcing a new security problem. When the candidate has been publicized, the details for this candidate will be provided.
CVE-2020-6829
When performing EC scalar point multiplication, the wNAF point multiplication algorithm was used; which leaked partial information about the nonce used during signature generation. Given an electro-magnetic trace of a few signature generations, the private key could have been computed. This vulnerability affects Firefox < 80 and Firefox for Android < 80.
