Mozilla NSS was updated to 3.29.5, bringing new features
and fixing bugs :

- 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

- 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

- 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

- 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_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

- 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

- 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

- NetLock Minositett Kozjegyzoi (Class QA)

- NetLock Kozjegyzoi (Class A) Tanusitvanykiado

- CVE-2016-2834: Memory safety bugs (boo#983639)
MFSA-2016-61 bmo#1206283 bmo#1221620 bmo#1241034

- Update to NSS 3.22.3

- Increase compatibility of TLS extended master secret,
don't send an empty TLS extension last in the handshake

- 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

- 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.
