+NSS 3.19.4 release notes
+========================
+
+`Introduction <#introduction>`__
+--------------------------------
+
+.. container::
+
+ Network Security Services (NSS) 3.19.4 is a patch release for NSS 3.19. The bug fixes in NSS
+ 3.19.4 are described in the "Security Advisories" section below.
+
+.. _distribution_information:
+
+`Distribution Information <#distribution_information>`__
+--------------------------------------------------------
+
+.. container::
+
+ The HG tag is NSS_3_19_4_RTM. NSS 3.19.4 requires NSPR 4.10.10 or newer.
+
+ NSS 3.19.4 and NSPR 4.10.10 source distributions are available on ftp.mozilla.org for secure
+ HTTPS download:
+
+ - Source tarballs:
+ https://ftp.mozilla.org/pub/mozilla.org/security/nss/releases/NSS_3_19_4_RTM/src/
+ https://ftp.mozilla.org/pub/nspr/releases/v4.10.10/src/
+
+.. _security_advisories:
+
+`Security Advisories <#security_advisories>`__
+----------------------------------------------
+
+.. container::
+
+ The following security-relevant bugs have been resolved in NSS 3.19.4. Users are encouraged to
+ upgrade immediately.
+
+ - `Bug 1192028 <https://bugzilla.mozilla.org/show_bug.cgi?id=1192028>`__ (CVE-2015-7181) and
+ `Bug 1202868 <https://bugzilla.mozilla.org/show_bug.cgi?id=1202868>`__ (CVE-2015-7182):
+ Several issues existed within the ASN.1 decoder used by NSS for handling streaming BER data.
+ While the majority of NSS uses a separate, unaffected DER decoder, several public routines
+ also accept BER data, and thus are affected. An attacker that successfully exploited these
+ issues can overflow the heap and may be able to obtain remote code execution.
+
+ | The following security-relevant bugs have been resolved in NSPR 4.10.10, which affect NSS.
+ | Because NSS includes portions of the affected NSPR code at build time, it is necessary to use
+ NSPR 4.10.10 when building NSS.
+
+ - `Bug 1205157 <https://bugzilla.mozilla.org/show_bug.cgi?id=1205157>`__ (NSPR, CVE-2015-7183):
+ A logic bug in the handling of large allocations would allow exceptionally large allocations
+ to be reported as successful, without actually allocating the requested memory. This may allow
+ attackers to bypass security checks and obtain control of arbitrary memory.
+
+.. _new_in_nss_3.19.4:
+
+`New in NSS 3.19.4 <#new_in_nss_3.19.4>`__
+------------------------------------------
+
+.. _new_functionality:
+
+`New Functionality <#new_functionality>`__
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. container::
+
+ No new functionality is introduced in this release. This is a patch release to fix
+ security-relevant bugs.
+
+`Compatibility <#compatibility>`__
+----------------------------------
+
+.. container::
+
+ NSS 3.19.4 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 3.19.4 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>`__ (product NSS). \ No newline at end of file
