Versions 1.0.0-rc3 through 1.2.7, 1.3.0-rc.1 through 1.3.2, and 1.4.0-rc.1 through 1.4.0-rc.2, due to insufficient checks when bind-mounting `/dev/pts/$n` to `/dev/console` inside the container, an attacker can trick runc into bind-mounting paths which would normally be made read-only or be masked onto a path that the attacker can write to. This attack is very similar in concept and application to CVE-2025-31133, except that it attacks a similar vulnerability in a different target (namely, the bind-mount of `/dev/pts/$n` to `/dev/console` as configured for all containers that allocate a console). This happens after `pivot_root(2)`, so this cannot be used to write to host files directly -- however, as with CVE-2025-31133, this can load to denial of service of the host or a container breakout by providing the attacker with a writable copy of `/proc/sysrq-trigger` or `/proc/sys/kernel/core_pattern` (respectively). This issue is fixed in versions 1.2.8, 1.3.3 and 1.4.0-rc.3."}, {"lang": "es", "value": "runc es una herramienta CLI para generar y ejecutar contenedores seg\u00fan la especificaci\u00f3n OCI. Las versiones 1.0.0-rc3 hasta la 1.2.7, 1.3.0-rc.1 hasta la 1.3.2, y 1.4.0-rc.1 hasta la 1.4.0-rc.2, debido a comprobaciones insuficientes al montar por enlace '/dev/pts/$n' a '/dev/console' dentro del contenedor, un atacante puede enga\u00f1ar a runc para que monte por enlace rutas que normalmente se har\u00edan de solo lectura o se enmascarar\u00edan en una ruta en la que el atacante pueda escribir. Este ataque es muy similar en concepto y aplicaci\u00f3n a CVE-2025-31133, excepto que ataca una vulnerabilidad similar en un objetivo diferente (es decir, el montaje por enlace de '/dev/pts/$n' a '/dev/console' tal como est\u00e1 configurado para todos los contenedores que asignan una consola). Esto ocurre despu\u00e9s de 'pivot_root(2)', por lo que esto no puede usarse para escribir directamente en archivos del host; sin embargo, al igual que con CVE-2025-31133, esto puede llevar a la denegaci\u00f3n de servicio del host o a un escape de contenedor al proporcionar al atacante una copia escribible de '/proc/sysrq-trigger' o '/proc/sys/kernel/core_pattern' (respectivamente).
