python: Python: Denial of Service via super-linear regular expression work in csv.Sniffer.sniff()

A flaw was found in the csv.Sniffer.sniff function within Python. An attacker can exploit this by providing specially crafted CSV samples, which can trigger super-linear regular-expression processing during dialect sniffing. This excessive processing consumes significant CPU resources, potentiall...
