Further exploitation (e.g., bypassing file permission checking or remote kernel code execution) is potentially possible, though this has not been demonstrated. In particular, release kernels are compiled with stack protection enabled, and some instances of the overflow are caught by this mechanism, causing a panic."}, {"lang": "es", "value": "En sistemas de 64 bits, la implementaci\u00f3n de VOP_VPTOFH() en los sistemas de archivos cd9660, tarfs y ext2fs desborda el b\u00fafer FID de destino en 4 bytes, lo que genera un desbordamiento del b\u00fafer de pila. Se puede hacer que un servidor NFS que exporta un sistema de archivos cd9660, tarfs o ext2fs entre en p\u00e1nico montando y accediendo a la exportaci\u00f3n con un cliente NFS. Es posible que se produzcan m\u00e1s explotaciones (por ejemplo, omitiendo la comprobaci\u00f3n de permisos de archivos o la ejecuci\u00f3n remota de c\u00f3digo del n\u00facleo), aunque esto no se ha demostrado.
