Descriptions

Integer overflow in the pipe_build_write_buffer function (sys/kern/sys_pipe.c) in the direct write optimization feature in the pipe implementation in FreeBSD 7.1 through 7.2 and 6.3 through 6.4 allows local users to bypass virtual-to-physical address lookups and read sensitive information in memory pages via unspecified vectors.

Desbordamiento de entero en la función pipe_build_write_buffer (sys/kern/sys_pipe.c) en la característica de escritura directa en la implementación del filtro en FreeBSD v7.1 hasta v7.2 y v6.3 hasta v6.4, permite a usuarios locales saltarse las búsquedas de direcciones virtual-to-physical, y leer información sensible en paginas de memoria a través de vectores no específicos.
