"The AlmaLinux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare
ALMALINUX9.6:CLSA-2026:1770717358 advisory.

  - Node.js versions which bundle an unpatched version of OpenSSL or run against a dynamically linked version
    of OpenSSL which are unpatched are vulnerable to the Marvin Attack -
    https://people.redhat.com/~hkario/marvin/, if PCKS #1 v1.5 padding is allowed when performing RSA
    descryption using a private key. (CVE-2023-46809)

  - node-tar is a Tar for Node.js. node-tar prior to version 6.2.1 has no limit on the number of sub-folders
    created in the folder creation process. An attacker who generates a large number of sub-folders can
    consume memory on the system running node-tar and even crash the Node.js client within few seconds of
    running it using a path with too many sub-folders inside. Version 6.2.1 fixes this issue by preventing
    extraction in excessively deep sub-folders. (CVE-2024-28863)

  - A memory leak could occur when a remote peer abruptly closes the socket without sending a GOAWAY
    notification. Additionally, if an invalid header was detected by nghttp2, causing the connection to be
    terminated by the peer, the same leak was triggered. This flaw could lead to increased memory consumption
    and potential denial of service under certain conditions. This vulnerability affects HTTP/2 Server users
    on Node.js v18.x, v20.x, v22.x and v23.x. (CVE-2025-23085)

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