Waitress denial of service vulnerability

Waitress is a WSGI Web Server Gateway Interface server for Python. A denial of service vulnerability exists in Waitress, which can be exploited to cause a denial of service by sending specially designed headers containing invalid characters that consume all available CPU resources...

Denial Of Service (DoS)

waitress is vulnerable to denial of service DoS. The vulnerability exists as catastrophic backtracking could occur through the use of a greedy regular expression that does not conform to RFC7230, and subsequently used to validate HTTP headers...
