Vulnerability Title
Python-Multipart: Negative Content-Length in parse_form buffers the entire body in memory
Vulnerability Description
Python-Multipart is a streaming multipart parser for Python. Prior to 0.0.31, parse_form() did not validate the Content-Length header before using it to bound its chunked read of the request body. A negative Content-Length turned the bounded read into a read-until-EOF, so the entire body was loaded into memory in a single read instead of in fixed-size chunks. This vulnerability is fixed in 0.0.31.

Vulnerability Title
Kludex python-multipart 输入验证错误漏洞
Vulnerability Description
Kludex python-multipart是Kludex的开源Web中间件流式解析库。 Kludex python-multipart 0.0.31之前版本存在输入验证错误漏洞,该漏洞源于parse_form()函数在将Content-Length标头用于限制请求体的分段读取之前未进行验证,可能导致负数的Content-Length将受限读取变为读取至文件结束符,从而将整个请求体一次性加载到内存中。
