firefox vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:

Ubuntu 18.10
Ubuntu 18.04 LTS
Ubuntu 16.04 LTS
Ubuntu 14.04 LTS
Summary
Firefox could be made to crash or run programs as your login if it opened a malicious website.

Software Description
firefox - Mozilla Open Source web browser
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, bypass CSP restrictions, spoof the protocol registration notification bar, leak SameSite cookies, bypass mixed content warnings, or execute arbitrary code. (CVE-2018-12388, CVE-2018-12390, CVE-2018-12392, CVE-2018-12393, CVE-2018-12398, CVE-2018-12399, CVE-2018-12401, CVE-2018-12402, CVE-2018-12403)

Multiple security issues were discovered with WebExtensions in Firefox. If a user were tricked in to installing a specially crafted extension, an attacker could potentially exploit these to bypass domain restrictions, gain additional privileges, or run content scripts in local pages without permission. (CVE-2018-12395, CVE-2018-12396, CVE-2018-12397)
