- Update to NSS 3.29.5 :
- MFSA 2017-11/CVE-2017-5461: Rare crashes in the base 64 decoder and encoder were fixed.
- MFSA 2017-11/CVE-2017-5462: A carry over bug in the RNG was fixed.
- CVE-2016-9574: Remote DoS during session handshake when using SessionTicket extention and ECDHE-ECDSA (bsc#1015499).
- requires NSPR >= 4.13.1
- Update to NSS 3.29.3
- enables TLS 1.3 by default
- Fixed a bug in hash computation (and build with GCC 7 which complains about shifts of boolean values).
(bsc#1030071, bmo#1348767)
- Update to NSS 3.28.3 This is a patch release to fix binary compatibility issues.
- Update to NSS 3.28.1 This is a patch release to update the list of root CA certificates.
- The following CA certificates were Removed CN = Buypass Class 2 CA 1 CN = Root CA Generalitat Valenciana OU = RSA Security 2048 V3
- The following CA certificates were Added OU = AC RAIZ FNMT-RCM CN = Amazon Root CA 1 CN = Amazon Root CA 2 CN = Amazon Root CA 3 CN = Amazon Root CA 4 CN = LuxTrust Global Root 2 CN = Symantec Class 1 Public Primary Certification Authority - G4 CN = Symantec Class 1 Public Primary Certification Authority - G6 CN = Symantec Class 2 Public Primary Certification Authority
- G4 CN = Symantec Class 2 Public Primary Certification Authority - G6
- The version number of the updated root CA list has been set to 2.11
- Update to NSS 3.28 New functionality :
- NSS includes support for TLS 1.3 draft -18. This includes a number of improvements to TLS 1.3 :
- The signed certificate timestamp, used in certificate transparency, is supported in TLS 1.3.
- Key exporters for TLS 1.3 are supported. This includes the early key exporter, which can be used if 0-RTT is enabled. Note that there is a difference between TLS 1.3 and key exporters in older versions of TLS. TLS 1.3 does not distinguish between an empty context and no context.
- The TLS 1.3 (draft) protocol can be enabled, by defining NSS_ENABLE_TLS_1_3=1 when building NSS.
- NSS includes support for the X25519 key exchange algorithm, which is supported and enabled by default in all versions of TLS. Notable Changes :
- NSS can no longer be compiled with support for additional elliptic curves. This was previously possible by replacing certain NSS source files.
- NSS will now detect the presence of tokens that support additional elliptic curves and enable those curves for use in TLS. Note that this detection has a one-off performance cost, which can be avoided by using the SSL_NamedGroupConfig function to limit supported groups to those that NSS provides.
- PKCS#11 bypass for TLS is no longer supported and has been removed.
- Support for 'export' grade SSL/TLS cipher suites has been removed.
- NSS now uses the signature schemes definition in TLS 1.3. This also affects TLS 1.2. NSS will now only generate signatures with the combinations of hash and signature scheme that are defined in TLS 1.3, even when negotiating TLS 1.2.
- This means that SHA-256 will only be used with P-256 ECDSA certificates, SHA-384 with P-384 certificates, and SHA-512 with P-521 certificates. SHA-1 is permitted (in TLS 1.2 only) with any certificate for backward compatibility reasons.
- NSS will now no longer assume that default signature schemes are supported by a peer if there was no commonly supported signature scheme.
- NSS will now check if RSA-PSS signing is supported by the token that holds the private key prior to using it for TLS.
- The certificate validation code contains checks to no longer trust certificates that are issued by old WoSign and StartCom CAs after October 21, 2016. This is equivalent to the behavior that Mozilla will release with Firefox 51.
- Update to NSS 3.27.2
- Fixed SSL_SetTrustAnchors leaks (bmo#1318561)
- raised the minimum softokn/freebl version to 3.28 as reported in (boo#1021636)
- Update to NSS 3.26.2 New Functionality :
- the selfserv test utility has been enhanced to support ALPN (HTTP/1.1) and 0-RTT
- added support for the System-wide crypto policy available on Fedora Linux see http://fedoraproject.org/wiki/Changes/CryptoPolicy
- introduced build flag NSS_DISABLE_LIBPKIX that allows compilation of NSS without the libpkix library Notable Changes :
- The following CA certificate was Added CN = ISRG Root X1
- NPN is disabled and ALPN is enabled by default
- the NSS test suite now completes with the experimental TLS 1.3 code enabled
- several test improvements and additions, including a NIST known answer test Changes in 3.26.2
- MD5 signature algorithms sent by the server in CertificateRequest messages are now properly ignored.
Previously, with rare server configurations, an MD5 signature algorithm might have been selected for client authentication and caused the client to abort the connection soon after.
- Update to NSS 3.25 New functionality :
- Implemented DHE key agreement for TLS 1.3
- Added support for ChaCha with TLS 1.3
- Added support for TLS 1.2 ciphersuites that use SHA384 as the PRF
- In previous versions, when using client authentication with TLS 1.2, NSS only supported certificate_verify messages that used the same signature hash algorithm as used by the PRF. This limitation has been removed.
Notable changes :
- An SSL socket can no longer be configured to allow both TLS 1.3 and SSLv3
- Regression fix: NSS no longer reports a failure if an application attempts to disable the SSLv2 protocol.
- The list of trusted CA certificates has been updated to version 2.8
- The following CA certificate was Removed Sonera Class1 CA
- The following CA certificates were Added Hellenic Academic and Research Institutions RootCA 2015 Hellenic Academic and Research Institutions ECC RootCA 2015 Certplus Root CA G1 Certplus Root CA G2 OpenTrust Root CA G1 OpenTrust Root CA G2 OpenTrust Root CA G3
- Update to NSS 3.24 New functionality :
- NSS softoken has been updated with the latest National Institute of Standards and Technology (NIST) guidance (as of 2015) :
- Software integrity checks and POST functions are executed on shared library load. These checks have been disabled by default, as they can cause a performance regression. To enable these checks, you must define symbol NSS_FORCE_FIPS when building NSS.
- Counter mode and Galois/Counter Mode (GCM) have checks to prevent counter overflow.
- Additional CSPs are zeroed in the code.
- NSS softoken uses new guidance for how many Rabin-Miller tests are needed to verify a prime based on prime size.
- NSS softoken has also been updated to allow NSS to run in FIPS Level 1 (no password). This mode is triggered by setting the database password to the empty string. In FIPS mode, you may move from Level 1 to Level 2 (by setting an appropriate password), but not the reverse.
- A SSL_ConfigServerCert function has been added for configuring SSL/TLS server sockets with a certificate and private key. Use this new function in place of SSL_ConfigSecureServer, SSL_ConfigSecureServerWithCertChain, SSL_SetStapledOCSPResponses, and SSL_SetSignedCertTimestamps. SSL_ConfigServerCert automatically determines the certificate type from the certificate and private key. The caller is no longer required to use SSLKEAType explicitly to select a 'slot' into which the certificate is configured (which incorrectly identifies a key agreement type rather than a certificate). Separate functions for configuring Online Certificate Status Protocol (OCSP) responses or Signed Certificate Timestamps are not needed, since these can be added to the optional SSLExtraServerCertData struct provided to SSL_ConfigServerCert. Also, partial support for RSA Probabilistic Signature Scheme (RSA-PSS) certificates has been added. Although these certificates can be configured, they will not be used by NSS in this version.
- Deprecate the member attribute authAlgorithm of type SSLCipherSuiteInfo. Instead, applications should use the newly added attribute authType.
- Add a shared library (libfreeblpriv3) on Linux platforms that define FREEBL_LOWHASH.
- Remove most code related to SSL v2, including the ability to actively send a SSLv2-compatible client hello. However, the server-side implementation of the SSL/TLS protocol still supports processing of received v2-compatible client hello messages.
- Disable (by default) NSS support in optimized builds for logging SSL/TLS key material to a logfile if the SSLKEYLOGFILE environment variable is set. To enable the functionality in optimized builds, you must define the symbol NSS_ALLOW_SSLKEYLOGFILE when building NSS.
- Update NSS to protect it against the Cachebleed attack.
- Disable support for DTLS compression.
- Improve support for TLS 1.3. This includes support for DTLS 1.3. Note that TLS 1.3 support is experimental and not suitable for production use.
- Update to NSS 3.23 New functionality :
- ChaCha20/Poly1305 cipher and TLS cipher suites now supported
- Experimental-only support TLS 1.3 1-RTT mode (draft-11).
This code is not ready for production use. Notable changes :
- The list of TLS extensions sent in the TLS handshake has been reordered to increase compatibility of the Extended Master Secret with with servers
- The build time environment variable NSS_ENABLE_ZLIB has been renamed to NSS_SSL_ENABLE_ZLIB
- 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

- CVE-2016-2834: Memory safety bugs (boo#983639) MFSA-2016-61 bmo#1206283 bmo#1221620 bmo#1241034 bmo#1241037
- Update to NSS 3.22.3
- Increase compatibility of TLS extended master secret, don't send an empty TLS extension last in the handshake (bmo#1243641)
- 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.
(CVE-2016-1950, bmo#1245528)
- Update to NSS 3.22.2 New functionality :
- RSA-PSS signatures are now supported (bmo#1215295)
- Pseudorandom functions based on hashes other than SHA-1 are now supported
- Enforce an External Policy on NSS from a config file (bmo#1009429)
- CVE-2016-8635: Fix for DH small subgroup confinement attack (bsc#1015547) Mozilla NSPR was updated to version 4.13.1: The previously released version 4.13 had changed pipes to be nonblocking by default, and as a consequence, PollEvent was changed to not block on clear. The NSPR development team received reports that these changes caused regressions in some applications that use NSPR, and it has been decided to revert the changes made in NSPR 4.13. NSPR 4.13.1 restores the traditional behavior of pipes and PollEvent. Mozilla NSPR update to version 4.13 had these changes :
- PL_strcmp (and others) were fixed to return consistent results when one of the arguments is NULL.
- PollEvent was fixed to not block on clear.
- Pipes are always nonblocking.
- PR_GetNameForIdentity: added thread safety lock and bound checks.
- Removed the PLArena freelist.
- Avoid some integer overflows.
- fixed several comments. This update also contains java-1_8_0-openjdk that needed to be rebuilt against the new mozilla-nss version.
Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
