Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:1951 advisory.

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)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
