python: Python: CPU Denial of Service in HTML parser via repeated unterminated markup declarations

A flaw was found in Python. Its incremental HTML parser can be exploited by a remote attacker. By sending specially crafted, uncontrolled data with repeated, incomplete markup declarations, the attacker can cause the system to consume excessive central processing unit CPU resources. This leads to...
