CVE-2022-45061
First published: Wed Nov 09 2022(Updated: )
A vulnerability was discovered in Python. A quadratic algorithm exists when processing inputs to the IDNA (RFC 3490) decoder, such that a crafted unreasonably long name being presented to the decoder could lead to a CPU denial of service. Hostnames are often supplied by remote servers that could be controlled by a malicious actor, which could trigger excessive CPU consumption on the client attempting to make use of an attacker-supplied hostname.
