  - JOSE is JSON Web Almost Everything - JWA, JWS, JWE, JWT, JWK, JWKS with no dependencies using runtime's
    native crypto in Node.js, Browser, Cloudflare Workers, Electron, and Deno. The PBKDF2-based JWE key
    management algorithms expect a JOSE Header Parameter named `p2c` PBES2 Count, which determines how many
    PBKDF2 iterations must be executed in order to derive a CEK wrapping key. The purpose of this parameter is
    to intentionally slow down the key derivation function in order to make password brute-force and
    dictionary attacks more expensive. This makes the PBES2 algorithms unsuitable for situations where the JWE
    is coming from an untrusted source: an adversary can intentionally pick an extremely high PBES2 Count
    value, that will initiate a CPU-bound computation that may take an unreasonable amount of time to finish.
    Under certain conditions, it is possible to have the user's environment consume unreasonable amount of CPU
    time. The impact is limited only to users utilizing the JWE decryption APIs with symmetric secrets to
    decrypt JWEs from untrusted parties who do not limit the accepted JWE Key Management Algorithms (`alg`
    Header Parameter) using the `keyManagementAlgorithms` (or `algorithms` in v1.x) decryption option or
    through other means. The `v1.28.2`, `v2.0.6`, `v3.20.4`, and `v4.9.2` releases limit the maximum PBKDF2
    iteration count to `10000` by default. It is possible to adjust this limit with a newly introduced
    `maxPBES2Count` decryption option. If users are unable to upgrade their required library version, they
    have two options depending on whether they expect to receive JWEs using any of the three PBKDF2-based JWE
    key management algorithms. They can use the `keyManagementAlgorithms` decryption option to disable
    accepting PBKDF2 altogether, or they can inspect the JOSE Header prior to using the decryption API and
    limit the PBKDF2 iteration count (`p2c` Header Parameter). (CVE-2022-36083)

Note that Nessus relies on the presence of the package as reported by the vendor.");
