Changelog:
The NSS team has released Network Security Services (NSS) 3.23, which is a minor
release.
The following security-relevant bug has been resolved in NSS 3.23.
Users are encouraged to upgrade immediately.
* Bug 1245528 (CVE-2016-1950):
Fixed a heap-based buffer overflow related to the parsing of certain ASN.1
structures. An attacker could create a specially-crafted certificate which,
when parsed by NSS, would cause a crash or execution of arbitrary code with
the permissions of the user.
New functionality:
* ChaCha20/Poly1305 cipher and TLS cipher suites now supported
(bug 917571, bug 1227905)
* Experimental-only support TLS 1.3 1-RTT mode (draft-11).
This code is not ready for production use.
New Functions:
* SSL_SetDowngradeCheckVersion - Set maximum version for new ServerRandom
anti-downgrade mechanism
Notable Changes:
* The copy of SQLite shipped with NSS has been updated to version 3.10.2
(bug 1234698)
* The list of TLS extensions sent in the TLS handshake has been reordered
to improve compatibility of the Extended Master Secret feature
with servers (bug 1243641)
* The build time environment variable NSS_ENABLE_ZLIB has been renamed
to NSS_SSL_ENABLE_ZLIB (Bug 1243872).
* The build time environment variable NSS_DISABLE_CHACHAPOLY was added,
which can be used to prevent compilation of the ChaCha20/Poly1305 code.
* The following CA certificates were Removed
- Staat der Nederlanden Root CA
- NetLock Minositett Kozjegyzoi (Class QA) Tanusitvanykiado
- NetLock Kozjegyzoi (Class A) Tanusitvanykiado
- NetLock Uzleti (Class B) Tanusitvanykiado
- NetLock Expressz (Class C) Tanusitvanykiado
- VeriSign Class 1 Public PCA – G2
- VeriSign Class 3 Public PCA
- VeriSign Class 3 Public PCA – G2
- CA Disig
* The following CA certificates were Added
- SZAFIR ROOT CA2
- Certum Trusted Network CA 2
* The following CA certificate had the Email trust bit turned on
- Actalis Authentication Root CA

CA certificates, are available at

NSS 3.15.1 release notes
Introduction
Network Security Services (NSS) 3.15.1 is a patch release for NSS 3.15. The bug fixes in NSS 3.15.1 are described in the "Bugs Fixed" section below.
Distribution Information
NSS 3.15.1 source distributions are also available on ftp.mozilla.org for secure HTTPS download:
Source tarballs:
https://ftp.mozilla.org/pub/mozilla.org/security/nss/releases/NSS_3_15_1_RTM/src/
New in NSS 3.15.1
New Functionality
TLS 1.2: TLS 1.2 (RFC 5246) is supported. HMAC-SHA256 cipher suites (RFC 5246 and RFC 5289) are supported, allowing TLS to be used without MD5 and SHA-1. Note the following limitations.
The hash function used in the signature for TLS 1.2 client authentication must be the hash function of the TLS 1.2 PRF, which is always SHA-256 in NSS 3.15.1.
AES GCM cipher suites are not yet supported.
New Functions
None.

in sslprot.h
SSL_LIBRARY_VERSION_TLS_1_2 - The protocol version of TLS 1.2 on the wire, value 0x0303.

Bug 875156 - Add const to the function arguments of SEC_CertNicknameConflict.
Bug 877798 - Fix ssltap to print the certificate_status handshake message correctly.
Bug 882829 - On Windows, NSS initialization fails if NSS cannot call the RtlGenRandom function.
Bug 875601 - SECMOD_CloseUserDB/SECMOD_OpenUserDB fails to reset the token delay, leading to spurious failures.
Bug 884072 - Fix a typo in the header include guard macro of secmod.h.
Bug 876352 - certutil now warns if importing a PEM file that contains a private key.
Bug 565296 - Fix the bug that shlibsign exited with status 0 even though it failed.
The NSS_SURVIVE_DOUBLE_BYPASS_FAILURE build option is removed.

Compatibility
NSS 3.15.1 shared libraries are backward compatible with all older NSS 3.x shared libraries. A program linked with older NSS 3.x shared libraries will work with NSS 3.15.1 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.

New in NSS 3.15
New Functionality
Support for OCSP Stapling (RFC 6066, Certificate Status Request) has been added for both client and server sockets. TLS client applications may enable this via a call to SSL_OptionSetDefault(SSL_ENABLE_OCSP_STAPLING, PR_TRUE);
Added function SECITEM_ReallocItemV2. It replaces function SECITEM_ReallocItem, which is now declared as obsolete.
Support for single-operation (eg: not multi-part) symmetric key encryption and decryption, via PK11_Encrypt and PK11_Decrypt.
certutil has been updated to support creating name constraints extensions.
New Functions
in ssl.h
SSL_PeerStapledOCSPResponse - Returns the server's stapled OCSP response, when used with a TLS client socket that negotiated the status_request extension.
SSL_SetStapledOCSPResponses - Set's a stapled OCSP response for a TLS server socket to return when clients send the status_request extension.
in ocsp.h
CERT_PostOCSPRequest - Primarily intended for testing, permits the sending and receiving of raw OCSP request/responses.
in secpkcs7.h
SEC_PKCS7VerifyDetachedSignatureAtTime - Verifies a PKCS#7 signature at a specific time other than the present time.
in xconst.h
CERT_EncodeNameConstraintsExtension - Matching function for CERT_DecodeNameConstraintsExtension, added in NSS 3.10.
in secitem.h
SECITEM_AllocArray
SECITEM_DupArray
SECITEM_FreeArray
SECITEM_ZfreeArray - Utility functions to handle the allocation and deallocation of SECItemArrays
SECITEM_ReallocItemV2 - Replaces SECITEM_ReallocItem, which is now obsolete. SECITEM_ReallocItemV2 better matches caller expectations, in that it updates item->len on allocation. For more details of the issues with SECITEM_ReallocItem, see Bug 298649 and Bug 298938.
in pk11pub.h
PK11_Decrypt - Performs decryption as a single PKCS#11 operation (eg: not multi-part). This is necessary for AES-GCM.
PK11_Encrypt - Performs encryption as a single PKCS#11 operation (eg: not multi-part). This is necessary for AES-GCM.
New Types
in secitem.h
SECItemArray - Represents a variable-length array of SECItems.
New Macros
in ssl.h
SSL_ENABLE_OCSP_STAPLING - Used with SSL_OptionSet to configure TLS client sockets to request the certificate_status extension (eg: OCSP stapling) when set to PR_TRUE
Notable Changes in NSS 3.15
SECITEM_ReallocItem is now deprecated. Please consider using SECITEM_ReallocItemV2 in all future code.
NSS has migrated from CVS to the Mercurial source control management system.
Updated build instructions are available at Migration to HG
As part of this migration, the source code directory layout has been re-organized.
The list of root CA certificates in the nssckbi module has been updated.
The default implementation of SSL_AuthCertificate has been updated to add certificate status responses stapled by the TLS server to the OCSP cache.
Applications that use SSL_AuthCertificateHook to override the default handler should add appropriate calls to SSL_PeerStapledOCSPResponse and CERT_CacheOCSPResponseFromSideChannel.
Bug 554369: Fixed correctness of CERT_CacheOCSPResponseFromSideChannel and other OCSP caching behaviour.
Bug 853285: Fixed bugs in AES GCM.
Bug 341127: Fix the invalid read in rc4_wordconv.
Faster NIST curve P-256 implementation.
Dropped (32-bit) SPARC V8 processor support on Solaris. The shared library libfreebl_32int_3.so is no longer produced.
