Vulnerability details

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…
