-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: nss, nss-util, and nspr security, bug fix, and enhancement update Advisory ID: RHSA-2016:0591-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2016-0591.html Issue date: 2016-04-05 CVE Names: CVE-2016-1978 CVE-2016-1979 ===================================================================== 1. Summary: An update for nss, nss-util, and nspr is now available for Red Hat Enterprise Linux 6. 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 Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, 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. The nss-util packages provide utilities for use with the Network Security Services (NSS) libraries. Netscape Portable Runtime (NSPR) provides platform independence for non-GUI operating system facilities. The following packages have been upgraded to a newer upstream version: nss 3.21.0, nss-util 3.21.0, nspr 4.11.0. (BZ#1300629, BZ#1299874, BZ#1299861) Security Fix(es): * A use-after-free flaw was found in the way NSS handled DHE (Diffie-Hellman key exchange) and ECDHE (Elliptic Curve Diffie-Hellman key exchange) handshake messages. A remote attacker could send a specially crafted handshake message that, when parsed by an application linked against NSS, would cause that application to crash or, under certain special conditions, execute arbitrary code using the permissions of the user running the application. (CVE-2016-1978) * A use-after-free flaw was found in the way NSS processed certain DER (Distinguished Encoding Rules) encoded cryptographic keys. An attacker could use this flaw to create a specially crafted DER encoded certificate which, when parsed by an application compiled against the NSS library, could cause that application to crash, or execute arbitrary code using the permissions of the user running the application. (CVE-2016-1979) Red Hat would like to thank the Mozilla Project for reporting these issues. Upstream acknowledges Eric Rescorla as the original reporter of CVE-2016-1978; and Tim Taubert as the original reporter of CVE-2016-1979. 4.
