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 conduct cross-site scripting (XSS) attacks,
bypass sandbox restrictions, obtain sensitive information, spoof the
origin of modal alerts, bypass same origin restrictions, read
uninitialized memory, cause a denial of service via program crash or hang,
or execute arbitrary code. (CVE-2017-7753, CVE-2017-7779, CVE-2017-7780,
