Descriptions

FreeBSD 7.1 through 8.1-PRERELEASE does not copy the read-only flag when creating a duplicate mbuf buffer reference, which allows local users to cause a denial of service (system file corruption) and gain privileges via the sendfile system call.

FreeBSD v7.1 a la v8.1-PRERELEASE no copia la bandera (flag) de solo lectura cuando crea una referencia duplicada del búfer mbuf, lo que permite a usuarios locales provocar una denegación de servicio (corrupción del sistema de ficheros) y la obtención de privilegios a través de una llamada al sistema sendfile.
