Descriptions

Multiple buffer overflows in Python 2.5.2 and earlier on 32bit platforms allow context-dependent attackers to cause a denial of service (crash) or have unspecified other impact via a long string that leads to incorrect memory allocation during Unicode string processing, related to the unicode_resize function and the PyMem_RESIZE macro.

Múltiples desbordamientos de búfer en Python 2.5.2 y anteriores en plataformas de 32bit. Permite a atacantes dependientes de contexto causar denegación de servicio (crash) o tener otros impactos no especificados a través de una cadena larga que conduce a una asignación incorrecta de memoria durante el procesamiento de la cadena Unicode, relacionado con la función unicode_resize y el macro PyMem_RESIZE.
