Name of the Vulnerable Software and Affected Versions Faucet SDN Ryu version 4.34

Description The issue allows attackers to cause a denial of service, resulting in an infinite loop, via a specific condition where length=0. This is related to the OFPHello function in the parser.py file.

Recommendations For Faucet SDN Ryu version 4.34, consider disabling the OFPHello function in parser.py to prevent the denial of service until a patch is available. Restrict access to the parser.py module to minimize the risk of exploitation. Avoid using the length=0 condition in the affected API endpoint until the issue is resolved.
