Name of the Vulnerable Software and Affected Versions Python versions prior to 3.5.10 Python versions prior to 3.6.12 Python versions prior to 3.7.9 Python versions prior to 3.8.4 Python versions prior to 3.9.0
Description The issue is related to the improper computation of hash values in the IPv4Interface and IPv6Interface classes in the Lib/ipaddress.py module of Python. This could allow a remote attacker to cause a denial of service if an application is affected by the performance of a dictionary containing IPv4Interface or IPv6Interface objects, and the attacker can cause many dictionary entries to be created.
Recommendations For versions prior to 3.5.10, update to version 3.5.10 or later. For versions prior to 3.6.12, update to version 3.6.12 or later. For versions prior to 3.7.9, update to version 3.7.9 or later. For versions prior to 3.8.4, update to version 3.8.4 or later. For versions prior to 3.9.0, update to version 3.9.0 or later.
