Descriptions

A use-after-free vulnerability during XSLT processing due to a failure to propagate error conditions during matching while evaluating context, leading to objects being used when they no longer exist. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 45.9, Firefox ESR < 52.1, and Firefox < 53.

Vulnerabilidad de uso de memoria previamente liberada durante el procesamiento XSLT debido al error para propagar condiciones de error durante el proceso de búsqueda de coincidencias mientras se evalúa el contexto, lo que conduce a que se empleen objetos cuando ya no existen. Esto resulta en un cierre inesperado potencialmente explotable. La vulnerabilidad afecta a Thunderbird en versiones anteriores a la 52.1, Firefox ESR en versiones anteriores a la 45.9, Firefox en versiones anteriores a la 52.1 y Firefox en versiones anteriores a la 53.
