Name of the Vulnerable Software and Affected Versions Firefox versions prior to 70 Thunderbird versions prior to 68.2 Firefox ESR versions prior to 68.2

Description The issue is related to a use-after-free error that occurs when following the value's prototype chain, allowing a reference to a locale to be retained, deleted, and then referenced again, resulting in a potentially exploitable crash. This could potentially allow a remote attacker to access confidential data, compromise its integrity, and cause a denial of service.
