opened a malicious website.

Software Description:

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 contents, bypass safebrowsing
protections, or execute arbitrary code. (CVE-2019-11709, CVE-2019-11710,
CVE-2019-11711, CVE-2019-11712, CVE-2019-11713, CVE-2019-11714,

It was discovered that Firefox treats all files in a directory as same
origin. If a user were tricked in to downloading a specially crafted HTML
file, an attacker could potentially exploit this to obtain sensitive
information from local files. (CVE-2019-11730)
