Original advisory details:

 Francis Gabriel discovered a buffer overflow during ASN.1 decoding in NSS.
 If a user were tricked in to opening a specially crafted website, an
 attacker could potentially exploit this to cause a denial of service via
 application crash, or execute arbitrary code with the privileges of the
 user invoking Firefox. (CVE-2016-1950)

 Bob Clary, Christoph Diehl, Christian Holler, Andrew McCreight, Daniel
 Holbert, Jesse Ruderman, Randell Jesup, Carsten Book, Gian-Carlo Pascutto,
 Tyson Smith, Andrea Marchesini, and Jukka Jylanki discovered multiple
 memory safety issues in Firefox. If a user were tricked in to opening a
 specially crafted website, an attacker could potentially exploit these to
 cause a denial of service via application crash, or execute arbitrary code
 with the privileges of the user invoking Firefox. (CVE-2016-1952,
 CVE-2016-1953)

 Nicolas Golubovic discovered that CSP violation reports can be used to
 overwrite local files. If a user were tricked in to opening a specially
 crafted website with addon signing disabled and unpacked addons installed,
 an attacker could potentially exploit this to gain additional privileges.
 (CVE-2016-1954)

 Muneaki Nishimura discovered that CSP violation reports contained full
 paths for cross-origin iframe navigations. An attacker could potentially
 exploit this to steal confidential data. (CVE-2016-1955)

 Ucha Gobejishvili discovered that performing certain WebGL operations
 resulted in memory resource exhaustion with some Intel GPUs, requiring
 a reboot. If a user were tricked in to opening a specially crafted
 website, an attacker could potentially exploit this to cause a denial
 of service. (CVE-2016-1956)

 Jose Martinez and Romina Santillan discovered a memory leak in
 libstagefright during MPEG4 video file processing in some circumstances.
 If a user were tricked in to opening a specially crafted website, an
 attacker could potentially exploit this to cause a denial of service via
 memory exhaustion. (CVE-2016-1957)

 Abdulrahman Alqabandi discovered that the addressbar could be blank or
 filled with page defined content in some circumstances. If a user were
 tricked in to opening a specially crafted website, an attacker could
 potentially exploit this to conduct URL spoofing attacks. (CVE-2016-1958)

 Looben Yang discovered an out-of-bounds read in Service Worker Manager. If
 a user were tricked in to opening a specially crafted website, an attacker
 could potentially exploit this to cause a denial of service via
 application crash, or execute arbitrary code with the privileges of the
 user invoking Firefox. (CVE-2016-1959)

 A use-after-free was discovered in the HTML5 string parser. If a user were
 tricked in to ... [Please see the references for more information on the vulnerabilities]");
