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)

package versions:
