Descriptions

Off-by-one error in the PyLocale_strxfrm function in Modules/_localemodule.c for Python 2.4 and 2.5 causes an incorrect buffer size to be used for the strxfrm function, which allows context-dependent attackers to read portions of memory via unknown manipulations that trigger a buffer over-read due to missing null termination.

Error de superación de límite (off-by-one) en la función PyLocale_strxfrm de Modules/_localemodule.c para Python 2.4 y 2.5 provoca que se utilice un tamaño de búfer incorrecto para la función strxfrm, lo cual permite a atacantes locales o remotos dependiendo del contexto leer porciones de memoria mediante manipulaciones desconocidas que disparan una lectura fuera de límite del búfer debido a la falta de una terminación null.
