Network Security Services is a set of libraries designed to support the cross-platform development of security-enabled client and server applications. Netscape Portable Runtime provides platform independence for non-GUI operating system facilities. The following packages have been upgraded to a later upstream version: nss , nss-softokn , nss-util , nspr . Security Fix: * nss: Out-of-bounds read when importing curve25519 private key * nss: Use-after-free in sftk_FreeSession due to improper refcounting * nss: Check length of inputs for cryptographic primitives * nss: Side channel attack on ECDSA signature generation * nss: P-384 and P-521 implementation uses a side-channel vulnerable modular inversion function * nss: ECDSA timing attack mitigation bypass * nss: Side channel vulnerabilities during RSA key generation * nss: CHACHA20-POLY1305 decryption with undersized tag leads to out-of-bounds read * nss: PKCS#1 v1.5 signatures can be used for TLS 1.3 * nss: TLS 1.3 HelloRetryRequest downgrade request sets client into invalid state For more details about the security issue, including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page listed in the References section. Bug Fix: * Memory leak: libcurl leaks 120 bytes on each connection * NSS does not set downgrade sentinel in ServerHello.random for TLS 1.0 and TLS 1.1 * Make TLS 1.3 work in FIPS mode * Name Constraints validation: CN treated as DNS name even when syntactically invalid as DNS name * x25519 allowed in FIPS mode * 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 * Running ipa-backup continuously causes httpd to crash and makes it irrecoverable * nss needs to comply to the new SP800-56A rev 3 requirements * KDF-self-tests-induced changes for nss in RHEL 7.9
