Description

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.
