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.
