Descriptions

The utf-16 decoder in Python 3.1 through 3.3 does not update the aligned_end variable after calling the unicode_decode_call_errorhandler function, which allows remote attackers to obtain sensitive information (process memory) or cause a denial of service (memory corruption and crash) via unspecified vectors.

El descodificador UTF-16 en Python v3.1 a v3.3 no actualiza la variable aligned_end después de llamar a la función unicode_decode_call_errorhandler, lo que permite a atacantes remotos obtener información sensible (la memoria del proceso) o provocar una denegación de servicio (por corrupción de memoria y caída la aplicación) a través de vectores no especificados.
