Denial of service in CBOR library

PeterO.Cbor versions 4.0.0 through 4.5.0 are vulnerable to a denial of

service vulnerability. An attacker may trigger the denial of service

condition by providing crafted data to the DecodeFromBytes or other

decoding mechanisms in PeterO.Cbor. Depending on the usage of the

library, an unauthenticated and remote attacker may be able to cause the

denial of service condition.
