Network Security Services (NSS) is a set of libraries designed to

In addition, the nspr package has been upgraded to upstream version
4.9.1, and the nss package has been upgraded to upstream version
3.13.5. These updates provide a number of bug fixes and enhancements
over the previous versions.
All NSS and NSPR users should upgrade to these updated packages, which
correct these issues and add these enhancements. After installing the
update, applications using NSS and NSPR must be restarted for the
changes to take effect.
