"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2024:0196 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2023-50967:
    latchset jose through version 11 allows attackers to cause a denial of service (CPU consumption) via a
    large p2c (aka PBES2 Count) value.

    CVE-2024-28176:
    jose is JavaScript module for JSON Object Signing and Encryption, providing support for JSON Web Tokens
    (JWT), JSON Web Signature (JWS), JSON Web Encryption (JWE), JSON Web Key (JWK), JSON Web Key Set (JWKS),
    and more. A vulnerability has
    been identified in the JSON Web Encryption (JWE) decryption interfaces, specifically related to the
    support for decompressing plaintext after its decryption. Under certain conditions it is possible to have
    the user's environment consume unreasonable amount of CPU time or memory during JWE Decryption operations.
    This issue has been patched in versions 2.0.7 and 4.15.5.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
