RHSA-2019:1951: Moderate: nss and nspr security, bug fix, and enhancement update

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 (3.44.0), nspr (4.21.0). (BZ#1713187, BZ#1713188)Security Fix(es): nss: NULL pointer dereference in several CMS functions resulting in a denial of service (CVE-2018-18508) nss: Out-of-bounds read when importing curve25519 private key (CVE-2019-11719) nss: Empty or malformed p256-ECDH public keys may trigger a segmentation fault (CVE-2019-11729) nss: PKCS#1 v1.5 signatures can be used for TLS 1.3 (CVE-2019-11727) 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): PQG verify fails when create DSA PQG parameters because the counts aren't returned correctly. (BZ#1685325) zeroization of AES context missing (BZ#1719629) RSA Pairwise consistency test (BZ#1719630) FIPS updated for nss-softoken POST (BZ#1722373) DH/ECDH key tests missing for the PG parameters (BZ#1722374) NSS should implement continuous random test on it's seed data or use the kernel AFALG interface for random (BZ#1725059) support setting supported signature algorithms in strsclnt utility (BZ#1725110) certutil -F with no parameters is killed with segmentation fault message (BZ#1725115) NSS: Support for IKE/IPsec typical PKIX usage so libreswan can use nss without rejecting certs based on EKU (BZ#1725116) NSS should use getentropy() for seeding its RNG, not /dev/urandom. Needs update to NSS 3.37 (BZ#1725117) Disable TLS 1.3 in FIPS mode (BZ#1725773) Wrong alert sent when client uses PKCS#1 signatures in TLS 1.3 (BZ#1728259) x25519 allowed in FIPS mode (BZ#1728260) post handshake authentication with selfserv does not work if SSLENABLESESSIONTICKETS is set (BZ#1728261) Enhancement(s): Move IKEv1 and IKEv2 KDF's from libreswan to nss-softkn (BZ#1719628)
