Description Andreas Stieger 2017-01-25 09:09:38 UTC

Security vulnerabilities fixed in Firefox 51
https://www.mozilla.org/en-US/security/advisories/mfsa2017-01/

Discovered by: Mustafa Hasan
The existence of a specifically requested local file can be found due to the double firing of the onerror when the source attribute on a  <track> tag refers to a file that does not exist if the source page is loaded locally.
