Python is an interpreted, interactive, object-oriented programming language.
An issue was discovered in urllib.request.AbstractBasicAuthHandler which allowed a remote attacker to send malicious data causing extensive regular expression backtracking.
An attacker could cause a possible Denial of Service condition.
There is no known workaround at this time.
