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, bypass same-origin restrictions, bypass CORS
restrictions, bypass CSRF protections, obtain sensitive information,
or execute arbitrary code. (CVE-2018-5156, CVE-2018-5186,
CVE-2018-5187, CVE-2018-5188, CVE-2018-12358, CVE-2018-12359,
CVE-2018-12360, CVE-2018-12361, CVE-2018-12362, CVE-2018-12363,
CVE-2018-12364, CVE-2018-12365, CVE-2018-12366, CVE-2018-12367,
CVE-2018-12370, CVE-2018-12371)

A security issue was discovered with WebExtensions. If a
user were tricked in to installing a specially crafted
extension, an attacker could potentially exploit this to
obtain full browser permissions. (CVE-2018-12369).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
