Security Bulletin: Vulnerabilities in Python below 3.9.16 affecting IBM Spectrum Protect Plus and its application agents for IBM Db2 and MongoDb2 using python.

Summary

CVEID: CVE-2022-45061 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. IBM Spectrum Protect Plus and its agent for IBM Db2 and MonfoDB will use Python 3.9.16 or one of the other version with the fix.
