Advisory ID:       RHSA-2019:1951-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://access.redhat.com/errata/RHSA-2019:1951
Issue date:        2019-07-30

                   CVE-2019-11729 
====================================================================
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)

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.
