Dear all,

Network Security Services (NSS) 3.79 was released on 31st May 2022.

This release fixes memory safety violations that can occur when parsing CMS data. We presume that with enough effort these memory safety violations are exploitable.

The HG tag is NSS_3_79_RTM. This version of NSS requires NSPR 4.34 or newer.

NSS 3.78.4 source distributions are available on ftp.mozilla.org for secure HTTPS download: <https://ftp.mozilla.org/pub/mozilla.org/security/nss/releases/NSS_3_79_RTM/src/>

Change:
   - Bug 205717 - Use PK11_GetSlotInfo instead of raw C_GetSlotInfo calls.
   - Bug 1766907 - Update mercurial in clang-format docker image.
   - Bug 1454072 - Use of uninitialized pointer in lg_init after alloc fail.
   - Bug 1769295 - selfserv and tstclnt should use PR_GetPrefLoopbackAddrInfo.
   - Bug 1753315 - Add SECMOD_LockedModuleHasRemovableSlots.
   - Bug 1387919 - Fix secasn1d parsing of indefinite SEQUENCE inside indefinite GROUP.
   - Bug 1765753 - Added RFC8422 compliant TLS <= 1.2 undefined/compressed ECPointFormat extension alerts.
   - Bug 1765753 - TLS 1.3 Server: Send protocol_version alert on unsupported ClientHello.legacy_version.
   - Bug 1764788 - Correct invalid record inner and outer content type alerts.
   - Bug 1757075 - NSS does not properly import or export pkcs12 files with large passwords and pkcs5v2 encoding.
   - Bug 1766978 - improve error handling after nssCKFWInstance_CreateObjectHandle.
   - Bug 1767590 - Initialize pointers passed to NSS_CMSDigestContext_FinishMultiple.
   - Bug 1769302 - NSS 3.79 should depend on NSPR 4.34  

NSS 3.79 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
