`Compatibility <#compatibility>`__

----------------------------------

.. container::

   NSS 3.77 shared libraries are backwards-compatible with all older NSS 3.x shared

   libraries. A program linked with older NSS 3.x shared libraries will work with

   this new version of the shared libraries without recompiling or

   relinking. Furthermore, applications that restrict their use of NSS APIs to the

   functions listed in NSS Public Functions will remain compatible with future

   versions of the NSS shared libraries.

`Feedback <#feedback>`__

------------------------

.. container::

   Bugs discovered should be reported by filing a bug report on

   `bugzilla.mozilla.org <https://bugzilla.mozilla.org/enter_bug.cgi?product=NSS>`__ (product NSS).

`Notes <#notes>`__

------------------

.. container::

   For users upgrading from NSS < 3.76.1 or NSS < 3.68.3, this release improves

   the stability of NSS when used in a multi-threaded environment. In

   particular, it fixes memory safety violations that can occur when PKCS#11

   tokens are removed while in use (CVE-2022-1097). We presume that with enough

   effort these memory safety violations are exploitable.
