NSS 3.68.3 (ESR) release notes¶
Network Security Services (NSS) 3.68.3 (ESR) was released on 28 March 2022.
The HG tag is NSS_3_68_3_RTM. NSS 3.68.3 requires NSPR 4.32 or newer.
NSS 3.68.3 source distributions are available on ftp.mozilla.org for secure HTTPS download:
Other releases are available Releases.
NSS 3.68.3 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.
Bugs discovered should be reported by filing a bug report on bugzilla.mozilla.org (product NSS).
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.
