Descriptions

Python before 3.3.4 RC1 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a file size value larger than the size of the zip file to the (1) ZipExtFile.read, (2) ZipExtFile.read(n), (3) ZipExtFile.readlines, (4) ZipFile.extract, or (5) ZipFile.extractall function.

Python anterior a 3.3.4 RC1 permite a atacantes remotos causar una denegación de servicio (bucle infinito y consumo de CPU) a través de un valor de tamaño de archivo más grande que el tamaño del archivo zip hacia la función (1) ZipExtFile.read, (2) ZipExtFile.read(n), (3) ZipExtFile.readlines, (4) ZipFile.extract o (5) ZipFile.extractall.
