"The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the
dla-3132 advisory.

  - The package org.yaml:snakeyaml from 0 and before 1.31 are vulnerable to Denial of Service (DoS) due
    missing to nested depth limitation for collections. (CVE-2022-25857)

  - Using snakeYAML to parse untrusted YAML files may be vulnerable to Denial of Service attacks (DOS). If the
    parser is running on user supplied input, an attacker may supply content that causes the parser to crash
    by stackoverflow. (CVE-2022-38749, CVE-2022-38750, CVE-2022-38751)

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