Network Security Services (NSS) is a set of libraries designed to support the cross-platform
development of security-enabled client and server applications.
Secu rit y Fixes
C VE- 2013- 174 0
A flaw was found in the way TLS False Start was implemented in NSS. An attacker could
use this flaw to potentially return unencrypted information from the server.
C VE- 2014 - 14 9 0
A race condition was found in the way NSS implemented session ticket handling as
specified by RFC 5077. An attacker could use this flaw to crash an application using NSS
or, in rare cases, execute arbitrary code with the privileges of the user running that
application.
C VE- 2014 - 14 9 1
It was found that NSS accepted weak D iffie-Hellman Key exchange (D HKE) parameters.
This could possibly lead to weak encryption being used in communication between the
client and the server.
C VE- 2014 - 154 5
An out-of-bounds write flaw was found in NSPR. A remote attacker could potentially use this
flaw to crash an application using NSPR or, possibly, execute arbitrary code with the
privileges of the user running that application. This NSPR flaw was not exposed to web
content in any shipped version of Firefox.
C VE- 2014 - 14 9 2
It was found that the implementation of Internationalizing D omain Names in Applications
(ID NA) hostname matching in NSS did not follow the RFC 6125 recommendations. This
could lead to certain invalid certificates with international characters to be accepted as
valid.
Red Hat would like to thank the Mozilla project for reporting the CVE-2014-1490, CVE-2014-1491, and

The nss and nspr packages have been upgraded to upstream version 3.16.1 and 4.10.6 respectively,
which provide a number of bug fixes and enhancements over the previous versions. (BZ #1110857,

B u g Fixes
B Z #1035281
Previously, when the output.log file was not present on the system, the shell in the Network
Security Services (NSS) specification handled test failures incorrectly as false positive test
results. Consequently, certain utilities, such as " grep" , could not handle failures properly.
This update improves error detection in the specification file, and " grep" and other utilities
now handle missing files or crashes as intended.
