RHSA-2016:0685: nss, nspr, nss-softokn, and nss-util security, bug fix, and enhancement update (Moderate)  

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#1310581, BZ#1303021, BZ#1299872)
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.
Bug Fix(es):
* The nss-softokn package has been updated to be compatible with NSS 3.21. (BZ#1326221)

Quick Help

Unknown Tests
There is a hardcoded maximum limit for number of tests displayed for a definition. For a small number of oval definitions, about ~1% of all, hundreds of test have been defined. This causes the pages to grow in size, exceed even 1mb, and they are unsuitable for display in a web page. So they are not displayed.Please refer to the xml definition files if you really want to view them.
