    =====================================================================
    
    1. Summary:
    
    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)

    described in this advisory, refer to:
    
    https://access.redhat.com/articles/11258
