NSS 3.78 Release

[Dennis Jackson]

Dear all,

Network Security Services (NSS) 3.78 was released on 28 April 2022.

The HG tag is NSS_3_78_RTM. This version of NSS requires NSPR 4.32 or newer.

NSS 3.78 source distributions are available on ftp.mozilla.org for secure HTTPS download: <https://ftp.mozilla.org/pub/mozilla.org/security/nss/releases/NSS_3_78_RTM/src/>

Change:

   - Bug 1755264 - Added TLS 1.3 zero-length inner plaintext checks and tests, zero-length record/fragment handling tests.
   - Bug 1294978 - Reworked overlong record size checks and added TLS1.3 specific boundaries.
   - Bug 1763120 - Add ECH Grease Support to tstclnt
   - Bug 1765003 - Add a strict variant of moz::pkix::CheckCertHostname.

NSS 3.78 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 at <https://bugzilla.mozilla.org/enter_bug.cgi?product=NSS>

Release notes will be available at <https://firefox-source-docs.mozilla.org/security/nss/releases/index.html> though you should expect a small delay.

Best,
Dennis
