Description
The issue is related to the implementation of the "data:" protocol in Mozilla Firefox, Firefox ESR, and the Thunderbird email client. It is associated with errors in the protocol's functioning on pages containing
iframe elements. Exploitation of this issue may allow a remote attacker to compromise the integrity of protected information. On pages with an iframe, the "data:" protocol can be used to create a modal alert that renders over arbitrary domains after page navigation, allowing the spoofing of the origin of the modal alert from the iframe content.Recommendations
For Thunderbird versions prior to 52.3, update to version 52.3 or later.
For Firefox ESR versions prior to 52.3, update to version 52.3 or later.
For Firefox versions prior to 55, update to version 55 or later.
