Descriptions

A buffer overflow can occur when rendering canvas content while adjusting the height and width of the canvas element dynamically, causing data to be written outside of the currently computed boundaries. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60, Thunderbird < 52.9, Firefox ESR < 60.1, Firefox ESR < 52.9, and Firefox < 61.

Puede ocurrir un desbordamiento de búfer al renderizar contenido canvas al ajustar dinámicamente la altura y anchura del elemento canvas, lo que provoca que los datos se escriban fuera de los límites calculados actualmente. Esto resulta en un cierre inesperado potencialmente explotable. La vulnerabilidad afecta a Thunderbird en versiones anteriores a la 60 y la 52.9, Firefox ESR en versiones anteriores a la 60.1 y la 52.9 y Firefox en versiones anteriores a la 61.
