    Denial of Service (DoS)

    com.upokecenter:cbor is a Java implementation of Concise Binary Object Representation.

    Affected versions of this package are vulnerable to Denial of Service (DoS) via an inefficient algorithm when a maliciously crafted input is passed to DecodeFromBytes or other CBOR decoding mechanisms.

    Workaround

    An input that decodes to a single CBOR object is not capable of containing a CBOR map if:

    1. It begins with a byte other than 0x80 through 0xDF, or
    2. It does not contain a byte in the range 0xa0 through 0xBF Such an input is not affected by this vulnerability and an application can choose to perform this check before passing it to a CBOR decoding mechanism.

    How to fix Denial of Service (DoS)?

    Upgrade com.upokecenter:cbor to version 4.5.2 or higher.
