Previous releases were released under a MPL 1.1/GPL + 2.0/LGPL 2.1 tri-license. For more information about MPL 2.0, please see + http://www.mozilla.org/MPL/2.0/FAQ.html. For an additional explantation on GPL/LGPL + compatibility, see security/nss/COPYING in the source code. + - Export and DES cipher suites are disabled by default. Non-ECC AES and Triple DES cipher suites + are enabled by default. + + NSS 3.14 source tarballs can be downloaded from + https://ftp.mozilla.org/pub/mozilla.org/security/nss/releases/NSS_3_14_RTM/src/. The CVS tag is + NSS_3_14_RTM. + +.. _new_in_nss_3.14: + +`New in NSS 3.14 <#new_in_nss_3.14>`__ +-------------------------------------- + +.. container:: + + The sections that follow discuss specific changes in NSS 3.14 in more detail. + + - Support for TLS 1.1 (RFC 4346) has been added + (https://bugzilla.mozilla.org/show_bug.cgi?id=565047). + + .. container:: + + To better support TLS 1.1 and future versions of TLS, a new version range API was + introduced to allow applications to specify the desired minimum and maximum versions. These + functions are intended to replace the now-deprecated use of the SSL_ENABLE_SSL3 and + SSL_ENABLE_TLS socket options. The following functions have been added to the libssl + library included in NSS 3.14 + + - SSL_VersionRangeGet (in ssl.h) + - SSL_VersionRangeGetDefault (in ssl.h) + - SSL_VersionRangeGetSupported (in ssl.h) + - SSL_VersionRangeSet (in ssl.h) + - SSL_VersionRangeSetDefault (in ssl.h) + + - To better ensure interoperability with peers that support TLS 1.1, NSS has altered how it + handles certain SSL protocol layer events. Such changes may present interoperability concerns + when enabling TLS 1.1. + + .. container:: + + - When connecting to a server, the record layer version of the initial ClientHello will be + at most { 3, 1 } (TLS 1.0), even when attempting to negotiate TLS 1.1 + (https://bugzilla.mozilla.org/show_bug.cgi?id=774547) + - The choice of client_version sent during renegotiations has changed. See the + "`Changes <#changes>`__" section below. + + - Experimental Support for DTLS (RFC 4347) and DTLS-SRTP (RFC 5764) + + DTLS client and server support has been added in NSS 3.14. Because the test coverage and + interoperability testing is not yet at the same level as other NSS code, this feature should + be considered "experimental" and may contain bugs. + + The following functions have been added to the libssl library included in NSS 3.14: + + - DTLS_ImportFD (in ssl.h) + - DTLS_GetHandshakeTimeout (in ssl.h) + - SSL_GetSRTPCipher (in ssl.h) + - SSL_SetRTPCiphers (in ssl.h) + + - Support for AES-GCM + + .. container:: + + Support for AES-GCM has been added to the NSS PKCS #11 module (softoken), based upon the + draft 7 of PKCS #11 v2.30. + + **WARNING**: Because of ambiguity in the current draft text, applications should ONLY use + GCM in single-part mode (C_Encrypt/C_Decrypt). They should NOT use multi-part APIs + (C_EncryptUpdate/C_DecryptUpdate). + + - Support for application-defined certificate chain validation callback when using libpkix + + .. container:: + + To better support per-application security policies, a new callback has been added for + applications that use libpkix to verify certificates. Applications may use this callback to + inform libpkix whether or not candidate certificate chains meet application-specific + security policies, allowing libpkix to continue discovering certificate paths until it can + find a chain that satisfies the policies. + + The following types have been added in NSS 3.14 + + - CERTChainVerifyCallback (in certt.h) + - CERTChainVerifyCallbackFunc (in certt.h) + - cert_pi_chainVerifyCallback, a new option for CERTValParamInType (in certt.h) + - A new error code: SEC_ERROR_APPLICATION_CALLBACK_ERROR (in secerr.h) + + - New for PKCS #11 + + .. container:: + + PKCS #11 mechanisms: + + - CKM_AES_CTS + - CKM_AES_CTR + - CKM_AES_GCM (see warnings against using C_EncryptUpdate/C_DecryptUpdate above) + - CKM_SHA224_KEY_DERIVATION + - CKM_SHA256_KEY_DERIVATION + - CKM_SHA384_KEY_DERIVATION + - CKM_SHA512_KEY_DERIVATION + + Changes in NSS 3.14 + +.. _changes_in_nss_3.14: + +`Changes in NSS 3.14 <#changes_in_nss_3.14>`__ +---------------------------------------------- + +.. container:: + + - `Bug 333601 <https://bugzilla.mozilla.org/show_bug.cgi?id=333601>`__ - Performance + enhancements for Intel Macs + + When building for Intel Macs, NSS will now take advantage of optimized assembly code for + common operations. These changes have the observed effect of doubling RSA performance. + + - `Bug 792681 <https://bugzilla.mozilla.org/show_bug.cgi?id=792681>`__ - New default cipher + suites + + The default cipher suites in NSS 3.14 have been changed to better reflect the current security + landscape. The defaults now better match the set that most major Web browsers enable by + default. + + - `Bug 783448 <https://bugzilla.mozilla.org/show_bug.cgi?id=783448>`__ - When performing an SSL + renegotiation, the client_version that is sent in the renegotiation ClientHello will be set to + match the client_version that was sent in the initial ClientHello. This is needed for + compatibility with IIS. + + - Certificate signatures that make use of the MD5 hash algorithm will now be rejected by + default. Support for MD5 may be manually enabled (but is discouraged) by setting the + environment variable of "NSS_HASH_ALG_SUPPORT=+MD5" or by using the NSS_SetAlgorithmPolicy + function. Note that SSL cipher suites with "MD5" in their names are NOT disabled by this + change; those cipher suites use HMAC-MD5, not plain MD5, and are still considered safe. + + - Maximum key sizes for RSA and Diffie-Hellman keys have been increased to 16K bits. + + - Command line utilities tstclnt, strsclnt, and selfserv have changed. The old options to + disable SSL 2, SSL 3 and TLS 1.0 have been removed and replaced with a new -V option that + specifies the enabled range of protocol versions (see usage output of those tools). + +.. _bugs_fixed_in_nss_3.14: + +`Bugs fixed in NSS 3.14 <#bugs_fixed_in_nss_3.14>`__ +---------------------------------------------------- + +.. container:: + + This Bugzilla query returns all the bugs fixed in NSS 3.14: + + https://bugzilla.mozilla.org/buglist.cgi?list_id=4643675;resolution=FIXED;classification=Components;query_format=advanced;product=NSS;target_milestone=3.14
