Descriptions

If Windows failed to duplicate a handle during process creation, the sandbox code may have inadvertently freed a pointer twice, resulting in a use-after-free and a potentially exploitable crash.
*This bug only affects Firefox on Windows when run in non-standard configurations (such as using `runas`). Other operating systems are unaffected.* This vulnerability affects Firefox < 118, Firefox ESR < 115.3, and Thunderbird < 115.3.

Si Windows no pudo duplicar un identificador durante la creación del proceso, es posible que el código de la sandbox puede haber liberado inadvertidamente un puntero dos veces, lo que resultó en un use-after-free y un bloqueo potencialmente explotable. *Este error sólo afecta a Firefox en Windows cuando se ejecuta en configuraciones no estándar (como el uso de `runas`). Otros sistemas operativos no se ven afectados.* Esta vulnerabilidad afecta a Firefox &lt; 118, Firefox ESR &lt; 115.3 y Thunderbird &lt; 115.3.
