Original advisory details:

 Multiple security issues were discovered in Firefox. If a user were
 tricked in to opening a specially crafted website, an attacker could
 potentially exploit these to read uninitialized memory, obtain sensitive
 information, bypass phishing and malware protection, spoof the origin in
 modal dialogs, conduct cross-site scripting (XSS) attacks, cause a denial
 of service via application crash, or execute arbitrary code.
 (CVE-2017-7793, CVE-2017-7810, CVE-2017-7811, CVE-2017-7812,
 CVE-2017-7813, CVE-2017-7814, CVE-2017-7815, CVE-2017-7818, CVE-2017-7819,
 CVE-2017-7820, CVE-2017-7822, CVE-2017-7823, CVE-2017-7824)

 Martin Thomson discovered that NSS incorrectly generated handshake hashes.
 A remote attacker could potentially exploit this to cause a denial of
 service via application crash, or execute arbitrary code. (CVE-2017-7805)

 Multiple security issues were discovered in WebExtensions. If a user were
 tricked in to installing a specially crafted extension, an attacker could
 potentially exploit these to download and open non-executable files
 without interaction, or obtain elevated privileges. (CVE-2017-7816,
 CVE-2017-7821)");
