Descriptions

Multiple integer overflows in Python 2.2.3 through 2.5.1, and 2.6, allow context-dependent attackers to have an unknown impact via a large integer value in the tabsize argument to the expandtabs method, as implemented by (1) the string_expandtabs function in Objects/stringobject.c and (2) the unicode_expandtabs function in Objects/unicodeobject.c. NOTE: this vulnerability reportedly exists because of an incomplete fix for CVE-2008-2315.

Múltiples desbordamientos de enteros en Python versiones 2.2.3 hasta 2.5.1 y 2.6, permiten a los atacantes dependiendo del contexto tener un impacto desconocido por medio de un valor entero largo en el argumento tabsize para el método expandtabs, tal y como es implementado por ( 1) la función string_expandtabs en el archivo Objects/stringobject.c y (2) la función unicode_expandtabs en el archivo Objects/unicodeobject.c. NOTA: esta vulnerabilidad se presenta debido a una corrección incompleta para el CVE-2008-2315.
