Descriptions

The plain text serializer used a fixed-size array for the number of <ol> elements it could process; however it was possible to overflow the static-sized array leading to memory corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71.

El serializador de texto plano utilizó una matriz de tamaño fijo para el número de elementos (ol) que podía procesar; sin embargo, fue posible desbordar la matriz de tamaño estático conllevando a un corrupción de la memoria y un bloqueo explotable potencialmente. Esta vulnerabilidad afecta a Thunderbird versiones anteriores a la versión 68.3, Firefox ESR versiones anteriores a la versión 68.3 y Firefox versiones anteriores a la versión 71.
