Original advisory details:
A sandbox escape was discovered in Firefox. If a user were tricked in to
installing a malicious language pack, an attacker could exploit this to
gain additional privileges. (CVE-2019-9811)
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, obtain sensitive
information, bypass same origin restrictions, conduct cross-site scripting
(XSS) attacks, conduct cross-site request forgery (CSRF) attacks, spoof
origin attributes, spoof the addressbar
