CVE-2007-4268

Integer signedness error in the Networking component in Apple Mac OS X 10.4 through 10.4.10 allows local users to execute arbitrary code via a crafted AppleTalk message with a negative value, which satisfies a signed comparison during mbuf allocation but is later interpreted as an unsigned value, which triggers a heap-based buffer overflow.

Un error en la propiedad signedness de enteros en el componente Networking en Apple Mac OS X versiones 10.4 hasta 10.4.10, permite a usuarios locales ejecutar código arbitrario por medio de un mensaje de AppleTalk diseñado con un valor negativo, que satisface una comparación firmada durante la asignación de mbuf pero que luego es interpretada como un valor sin firmar, lo que desencadena un desbordamiento de búfer en la región heap de la memoria.
