Red Hat Security Advisory

 

Synopsis: Moderate: nss and nspr security, bug fix, and enhancement update

Advisory ID: RHSA-2016:0684-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2016-0684.html

Issue date: 2016-04-25

CVE Names: CVE-2016-1978 CVE-2016-1979

=====================================================================

 

1. Summary:

 

An update for nss and nspr is now available for Red Hat Enterprise Linux 5.

 

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 (v. 5 server) - i386, ia64, ppc, s390x, x86_64

Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64

Red Hat Enterprise Linux Desktop Workstation (v. 5 client) - 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. 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, nspr 4.11.0. (BZ#1297944, BZ#1297943)

 

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. 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. Bugs fixed (https://bugzilla.redhat.com/):

 

1297943 - Rebase RHEL 5.11.z to NSPR 4.11 in preparation for Firefox 45.

1297944 - Rebase RHEL 5.11.z to NSS 3.21 in preparation for Firefox 45.

1315202 - CVE-2016-1979 nss: Use-after-free during processing of DER encoded keys in NSS (MFSA 2016-36)

1315565 - CVE-2016-1978 nss: Use-after-free in NSS during SSL connections in low memory (MFSA 2016-15)
