`Compatibility <#compatibility>`__
----------------------------------
.. container::
NSS 3.76.1 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.

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.
