Inefficient algorithmic complexity in DecodeFromBytes function in com.upokecenter.cbor Java implementation of Concise Binary Object Representation (CBOR) versions 4.0.0 to 4.5.1 allows an attacker to cause a denial of service by passing a maliciously crafted input. Depending on an application's use of this library, this may be a remote attacker.
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.
