| 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), nss-softokn (3.53.1), nss-util (3.53.1), nspr (4.25.0). (BZ#1804262, BZ#1804264, BZ#1804271, BZ#1804273)
Security Fix(es):
nss: Out-of-bounds read when importing curve25519 private key (CVE-2019-11719)
nss: Use-after-free in sftk_FreeSession due to improper refcounting (CVE-2019-11756)
nss: Check length of inputs for cryptographic primitives (CVE-2019-17006)
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: ECDSA timing attack mitigation bypass (CVE-2020-12401)
nss: Side channel vulnerabilities during RSA key generation (CVE-2020-12402)
nss: CHACHA20-POLY1305 decryption with undersized tag leads to out-of-bounds read (CVE-2020-12403)
nss: PKCS#1 v1.5 signatures can be used for TLS 1.3 (CVE-2019-11727)
nss: TLS 1.3 HelloRetryRequest downgrade request sets client into invalid state (CVE-2019-17023)

Bug Fix(es):
Memory leak: libcurl leaks 120 bytes on each connection (BZ#1688958)
NSS does not set downgrade sentinel in ServerHello.random for TLS 1.0 and TLS 1.1 (BZ#1712924)
Make TLS 1.3 work in FIPS mode (BZ#1724251)
Name Constraints validation: CN treated as DNS name even when syntactically invalid as DNS name (BZ#1737910)
x25519 allowed in FIPS mode (BZ#1754518)
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 (BZ#1779325)
Running ipa-backup continuously causes httpd to crash and makes it irrecoverable (BZ#1804015)
nss needs to comply to the new SP800-56A rev 3 requirements (BZ#1857308)
