Detail
Problem Description: An update for nss and nspr 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. 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 AF_ALG 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 SSL_ENABLE_SESSION_TICKETS is set (BZ#1728261) Enhancement(s): * Move IKEv1 and IKEv2 KDF's from libreswan to nss-softkn (BZ#1719628) 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 After installing this update, applications using NSS or NSPR (for example, Firefox) must be restarted for this update to take effect. 5.
