CVE-2016-5268 (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 does not properly set the LINKABLE and URI_SAFE_FOR_UNTRUSTED_CONTENT flags of about: URLs that are used for error pages, which makes it easier for remote attackers to conduct spoofing attacks via a crafted URL, as demonstrated by misleading text after an about:neterror?d= substring.
