Inefficient Algorithmic Complexity


Severity High
Score 7.5/10


Inefficient algorithmic complexity in DecodeFromBytes function in "com.upokecenter.cbor" Java implementation of Concise Binary Object Representation (CBOR) versions 4.0.x prior to 4.5.1 allows an attacker to cause a Denial of Service (DOS) by passing a maliciously crafted input. Depending on an application's use of this library, this may be a remote attacker.

CWE-407 - Inefficient Algorithmic Complexity

An algorithm in a product has an inefficient worst-case computational complexity that may be detrimental to system performance and can be triggered by an attacker, typically using crafted manipulations that ensure that the worst case is being reached.
