Descriptions

The vm_map_lookup function in sys/vm/vm_map.c in the mmap implementation in the kernel in FreeBSD 9.0 through 9.1-RELEASE-p4 does not properly determine whether a task should have write access to a memory location, which allows local users to bypass filesystem write permissions and consequently gain privileges via a crafted application that leverages read permissions, and makes mmap and ptrace system calls.

La función vm_map_lookup en sys/vm/vm_map.c
en la ejecución de "mmap" en el kernel en FreeBSD v9.0 hasta v9.1-RELEASE-p4 no determina correctamente si una tarea debe tener acceso de escritura a una posición de memoria, que permite a los usuarios locales saltarse permisos de escritura del sistema de archivos y por lo tanto obtener privilegios a través de una aplicación manipulada que aprovecha permisos de lectura, y que hace llamadas al sistema "mmap" y "ptrace".
