Bugzilla:
1361987: CVE-2016-5262 Mozilla: Scripts on marquee tag can execute in sandboxed iframes (MFSA 2016-76)

The MITRE CVE dictionary describes this issue as:

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.
