Description Andreas Stieger 2016-04-27 08:56:44 UTC

Mozilla engineer Mark Goodwin discovered that the Firefox Health Report (about:healthreport) accepts certain events from any content document present in the remote-report iframe. If there were another vulnerability that allowed the injection of web content into the Firefox Health Report iframe, this content could change the sharing preferences of a user by firing the appropriate events at it s containing page. 

FHR accepts events from untrusted domains (CVE-2016-2820)

openSUSE only.
