Python stringobject.c多个远程溢出漏洞
Vulnerability Description
Python是一种开放源代码的脚本编程语言。 Python的核心API提供了多个用于分配字符串对象的函数，其中一个API调用允许分配或重新分配PyStringObject，这个函数为PyString_FromStringAndSize()，该函数获取了两个参数，分别为一个指针和一个有符整数。如果指针非空的话，就会将指向该指针的内存重新分配为第二个参数所指定的大小；如果指针为空，就会分配整数所指定的字节数并返回。 在这个操作期间，没有验证第二个参数是否为负数，而该值与PyStringObject的大小相加并
