`Notable Changes in NSS 3.33 <#notable_changes_in_nss_3.33>`__
--------------------------------------------------------------
.. container::
- TLS compression is no longer supported. API calls that attempt to enable compression are
accepted without failure. However, TLS compression will remain disabled.
- This version of NSS uses a `formally verified
implementation <https://blog.mozilla.org/security/2017/09/13/verified-cryptography-firefox-57/>`__
of Curve25519 on 64-bit systems.
- The compile time flag DISABLE_ECC has been removed.
- When NSS is compiled without NSS_FORCE_FIPS=1 startup checks are no longer performed.
- Fixes CVE-2017-7805, a potential use-after-free in TLS 1.2 server, when verifying client
authentication.
- Various minor improvements and correctness fixes.
.. _new_in_nss_3.33:
`New in NSS 3.33 <#new_in_nss_3.33>`__
--------------------------------------
.. _new_functionality:
`New Functionality <#new_functionality>`__
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. container::
- When listing an NSS database, using certutil -L, and the database hasn't yet been initialized
with any non-empty or empty password, the text "Database needs user init" will be included in
the listing.
- When using certutil to set an inacceptable password in FIPS mode, a correct explanation of
acceptable passwords will be printed.
.. rubric:: New Functions
:name: new_functions
- *in cert.h*
- **CERT_FindCertByIssuerAndSNCX** - a variation of existing function
CERT_FindCertByIssuerAndSN that accepts an additional password context parameter.
- **CERT_FindCertByNicknameOrEmailAddrCX** - a variation of existing function
CERT_FindCertByNicknameOrEmailAddr that accepts an additional password context parameter.
- **CERT_FindCertByNicknameOrEmailAddrForUsageCX** - a variation of existing function
CERT_FindCertByNicknameOrEmailAddrForUsage that accepts an additional password context
parameter.
- *in secport.h*
- **NSS_SecureMemcmpZero** - check if a memory region is all zero in constant time.
- **PORT_ZAllocAligned** - allocate aligned memory.
- **PORT_ZAllocAlignedOffset** - allocate aligned memory for structs.
- *in ssl.h*
- **SSL_GetExperimentalAPI** - access experimental APIs in libssl.
.. _bugs_fixed_in_nss_3.33:
`Bugs fixed in NSS 3.33 <#bugs_fixed_in_nss_3.33>`__
----------------------------------------------------
.. container::
This Bugzilla query returns all the bugs fixed in NSS 3.33:
https://bugzilla.mozilla.org/buglist.cgi?resolution=FIXED&classification=Components&query_format=advanced&product=NSS&target_milestone=3.33
`Compatibility <#compatibility>`__
----------------------------------
.. container::
NSS 3.33 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 3.33 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 <#feedback>`__
------------------------
.. container::
Bugs discovered should be reported by filing a bug report with
`bugzilla.mozilla.org <https://bugzilla.mozilla.org/enter_bug.cgi?product=NSS>`__ (select product
'NSS').
