Descriptions

Integer signedness error in select() on OpenBSD 3.1 and earlier allows local users to overwrite arbitrary kernel memory via a negative value for the size parameter, which satisfies the boundary check as a signed integer, but is later used as an unsigned integer during a data copying operation.

Error de falta de signo en entero en select() de OpenBSD 3.1 y anteriores permite a usuarios locales sobreescribir memoria del kernel arbitraria mediante un valor negativo en el parámetro de tamaño, que satisface la comprobación de límites de entero con signo, pero que es usado luego como un entero sin signo durante una operación de copia de datos.
