A flaw was found in urllib3 Python library that could lead to a Denial of Service condition. A remote, malicious server can exploit this flaw by responding to a client request with an HTTP message that uses an excessive number of chained compression algorithms. This unlimited decompression chain causes the client system to consume a virtually unbounded amount of CPU resources and memory. The high resource usage leads to service disruption, making the application unresponsive.
