CVE-2022-45061

CVE-2022-45061, high severity (CVSS 7.5): 3 tracked apps concerned, all fixed or indeterminable on their current version.

Severity (CVSS): 7.5
Exploitation: 2.7 %
Tracked apps: 3
Still exposed: 0

Published on 2022-11-09

An issue was discovered in Python before 3.11.1. An unnecessary quadratic algorithm exists in one path when processing some 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; in such a scenario, they could trigger excessive CPU consumption on the client attempting to make use of an attacker-supplied supposed hostname. For example, the attack payload could be placed in the Location header of an HTTP response with status code 302. A fix is planned in 3.11.1, 3.10.9, 3.9.16, 3.8.16, and 3.7.16.
