Descriptions

Python 2.5.2 and earlier allows context-dependent attackers to execute arbitrary code via multiple vectors that cause a negative size value to be provided to the PyString_FromStringAndSize function, which allocates less memory than expected when assert() is disabled and triggers a buffer overflow.

Python versión 2.5.2 y anteriores, permite a los atacantes dependiendo del contexto ejecutar código arbitrario por medio de varios vectores que causan que se proporcione un valor de tamaño negativo a la función PyString_FromStringAndSize, que asigna menos memoria de la esperada cuando assert() está deshabilitado y desencadena un desbordamiento de búfer.
