CentOS Errata and Security Advisory CESA-2016:2779
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.
The following packages have been upgraded to a newer upstream version: nss
(3.21.3), nss-util (3.21.3).
Security Fix(es):
Multiple buffer handling flaws were found in the way NSS handled cryptographic
data from the network. A remote attacker could use these flaws to crash an
application using NSS or, possibly, execute arbitrary code with the permission
of the user running the application. (CVE-2016-2834)
A NULL pointer dereference flaw was found in the way NSS handled invalid
Diffie-Hellman keys. A remote client could use this flaw to crash a TLS/SSL
server using NSS. (CVE-2016-5285)
It was found that Diffie Hellman Client key exchange handling in NSS was
vulnerable to small subgroup confinement attack. An attacker could use this flaw
to recover private keys by confining the client DH key to small subgroup of the
desired group. (CVE-2016-8635)
Red Hat would like to thank the Mozilla project for reporting CVE-2016-2834. The
CVE-2016-8635 issue was discovered by Hubert Kario (Red Hat). Upstream
acknowledges Tyson Smith and Jed Davis as the original reporter of
CVE-2016-2834.
