    Security Fixes in NSS 3.21

    New in NSS 3.21

    New Functionality

    • certutil now supports a --rename option to change a nickname (bug 1142209)
    • TLS extended master secret extension (RFC 7627) is supported (bug 1117022)
    • New info functions added for use during mid-handshake callbacks (bug 1084669)

    New Functions

    • in nss.h
      • NSS_OptionSet - sets NSS global options
      • NSS_OptionGet - gets the current value of NSS global options
    • in secmod.h
      • SECMOD_CreateModuleEx - Create a new SECMODModule structure from module name string, module parameters string, NSS specific parameters string, and NSS configuration parameter string. The module represented by the module structure is not loaded. The difference with SECMOD_CreateModule is the new function handles NSS configuration parameter strings.
    • in ssl.h
      • SSL_GetPreliminaryChannelInfo - obtains information about a TLS channel prior to the handshake being completed, for use with the callbacks that are invoked during the handshake
      • SSL_SignaturePrefSet - configures the enabled signature and hash algorithms for TLS
      • SSL_SignaturePrefGet - retrieves the currently configured signature and hash algorithms
      • SSL_SignatureMaxCount - obtains the maximum number signature algorithms that can be configured with SSL_SignaturePrefSet
    • in utilpars.h
      • NSSUTIL_ArgParseModuleSpecEx - takes a module spec and breaks it into shared library string, module name string, module parameters string, NSS specific parameters string, and NSS configuration parameter strings. The returned strings must be freed by the caller. The difference with NSS_ArgParseModuleSpec is the new function handles NSS configuration parameter strings.
      • NSSUTIL_MkModuleSpecEx - take a shared library string, module name string, module parameters string, NSS specific parameters string, and NSS configuration parameter string and returns a module string which the caller must free when it is done. The difference with NSS_MkModuleSpec is the new function handles NSS configuration parameter strings.

    New Types

    • in pkcs11t.h
      • CK_TLS12_MASTER_KEY_DERIVE_PARAMS{_PTR} - parameters {or pointer} for CKM_TLS12_MASTER_KEY_DERIVE
      • CK_TLS12_KEY_MAT_PARAMS{_PTR} - parameters {or pointer} for CKM_TLS12_KEY_AND_MAC_DERIVE
      • CK_TLS_KDF_PARAMS{_PTR} - parameters {or pointer} for CKM_TLS_KDF
      • CK_TLS_MAC_PARAMS{_PTR} - parameters {or pointer} for CKM_TLS_MAC
    • in sslt.h
      • SSLHashType - identifies a hash function
      • SSLSignatureAndHashAlg - identifies a signature and hash function
      • SSLPreliminaryChannelInfo - provides information about the session state prior to handshake completion

    New Macros

    • in nss.h
      • NSS_RSA_MIN_KEY_SIZE - used with NSS_OptionSet and NSS_OptionGet to set or get the minimum RSA key size
      • NSS_DH_MIN_KEY_SIZE - used with NSS_OptionSet and NSS_OptionGet to set or get the minimum DH key size
      • NSS_DSA_MIN_KEY_SIZE - used with NSS_OptionSet and NSS_OptionGet to set or get the minimum DSA key size
    • in pkcs11t.h
      • CKM_TLS12_MASTER_KEY_DERIVE - derives TLS 1.2 master secret
      • CKM_TLS12_KEY_AND_MAC_DERIVE - derives TLS 1.2 traffic key and IV
      • CKM_TLS12_MASTER_KEY_DERIVE_DH - derives TLS 1.2 master secret for DH (and ECDH) cipher suites
      • CKM_TLS12_KEY_SAFE_DERIVE and CKM_TLS_KDF are identifiers for additional PKCS#12 mechanisms for TLS 1.2 that are currently unused in NSS.
      • CKM_TLS_MAC - computes TLS Finished MAC
    • in secoidt.h
      • NSS_USE_ALG_IN_SSL_KX - policy flag indicating that keys are used in TLS key exchange
    • in sslerr.h
      • SSL_ERROR_RX_SHORT_DTLS_READ - error code for failure to include a complete DTLS record in a UDP packet
      • SSL_ERROR_NO_SUPPORTED_SIGNATURE_ALGORITHM - error code for when no valid signature and hash algorithm is available
      • SSL_ERROR_UNSUPPORTED_SIGNATURE_ALGORITHM - error code for when an unsupported signature and hash algorithm is configured
      • SSL_ERROR_MISSING_EXTENDED_MASTER_SECRET - error code for when the extended master secret is missing after having been negotiated
      • SSL_ERROR_UNEXPECTED_EXTENDED_MASTER_SECRET - error code for receiving an extended master secret when previously not negotiated
    • in sslt.h
      • SSL_ENABLE_EXTENDED_MASTER_SECRET - configuration to enable the TLS extended master secret extension (RFC 7627)
      • ssl_preinfo_version - used with SSLPreliminaryChannelInfo to indicate that a TLS version has been selected
      • ssl_preinfo_cipher_suite - used with SSLPreliminaryChannelInfo to indicate that a TLS cipher suite has been selected
      • ssl_preinfo_all - used with SSLPreliminaryChannelInfo to indicate that all preliminary information has been set

    The NSS development team would like to thank Karthikeyan Bhargavan from INRIA for responsibly disclosing the issue in Bug 1158489.

    Compatibility

    NSS 3.21 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 3.21 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.

    Feedback

    Bugs discovered should be reported by filing a bug report with bugzilla.mozilla.org (product NSS).
