Kerentanan Loop with Unreachable Exit Condition ('Infinite Loop') pada yubico yubihsm connector, fedoraproject fedora. Skor CVSS 3.1 7.5 (High) menurut NVD.

Deskripsi (NVD)

An issue was discovered in the /api/connector endpoint handler in Yubico yubihsm-connector before 3.0.1 (in YubiHSM SDK before 2021.04). The handler did not validate the length of the request, which can lead to a state where yubihsm-connector becomes stuck in a loop waiting for the YubiHSM to send it data, preventing any further operations until the yubihsm-connector is restarted. An attacker can send 0, 1, or 2 bytes to trigger this.
