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 cause a denial of service, read uninitialized
 memory, obtain sensitive information, bypass same-origin restrictions,
 bypass CSP protections, bypass mixed content blocking, spoof the
 addressbar, or execute arbitrary code. (CVE-2017-7826, CVE-2017-7827,
 CVE-2017-7828, CVE-2017-7830, CVE-2017-7831, CVE-2017-7832, CVE-2017-7833,
 CVE-2017-7834, CVE-2017-7835, CVE-2017-7837, CVE-2017-7838, CVE-2017-7842)

 It was discovered that javascript: URLs pasted in to the addressbar
 would be executed instead of being blocked in some circumstances. If a
 user were tricked in to copying a specially crafted URL in to the
 addressbar, an attacker could potentially exploit this to conduct
 cross-site scripting (XSS) attacks. (CVE-2017-7839)

 It was discovered that exported bookmarks do not strip script elements
 from user-supplied tags. If a user were tricked in to adding specially
 crafted tags to bookmarks, exporting them and then opening the resulting
 HTML file, an attacker could potentially exploit this to conduct
 cross-site scripting (XSS) attacks. (CVE-2017-7840)");
