Name of the Vulnerable Software and Affected Versions Firefox versions prior to 55 Firefox ESR versions prior to 52.3 Thunderbird versions prior to 52.3

Description A use-after-free issue occurs when re-computing layout for a "marquee" element during window resizing, where the updated style object is freed while still in use, resulting in a potentially exploitable crash. This can be exploited by a remote attacker to cause a denial of service.

Recommendations For Firefox versions prior to 55, update to version 55 or later. For Firefox ESR versions prior to 52.3, update to version 52.3 or later. For Thunderbird versions prior to 52.3, update to version 52.3 or later.
