Comment (by ralva83702):

 Are you saying this patch is going to require php 7? In my case $mime is
 getting set to "application/octet-stream"  right before the change on line
 2393 so just checking that it's false isn't doing anything but returning
 false for svg files and still showing the security error.

 > While not documented, application/octet-stream is the expected result
 when image_type_to_mime_type is called with something that isn't one of
 the constants:
 > {{{#!php
 > default:
 >     return "application/octet-stream"; /* suppose binary format */
 > }}}
 > (as seen in https://github.com/php/php-
 > In our specific case it is called with "false", since exif-imagetype
 cant detect svg.
