CVE-2022-31124: Possible leak of key's raw field if declared length is incorrect
(updated )
If a field of a key is shorter than it is declared to be, the parser raises an error with a message containing the raw field value. An attacker able to modify the declared length of a key’s sensitive field can thus expose the raw value of that field.
