CWE-79  (opens in a new tab)

How to fix?

Upgrade Ubuntu:16.04 firefox to version 48.0+build2-0ubuntu0.16.04.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream firefox package and not the firefox package as distributed by Ubuntu. See How to fix? for Ubuntu:16.04 relevant fixed versions and status.

Mozilla Firefox before 48.0 and Firefox ESR 45.x before 45.3 process JavaScript event-handler attributes of a MARQUEE element within a sandboxed IFRAME element that lacks the sandbox="allow-scripts" attribute value, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via a crafted web site.
