"The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as
referenced in the SUSE-SU-2022:2108-1 advisory.

  - The actionpack ruby gem before 6.1.3.2, 6.0.3.7, 5.2.4.6, 5.2.6 suffers from a possible denial of service
    vulnerability in the Token Authentication logic in Action Controller due to a too permissive regular
    expression. Impacted code uses `authenticate_or_request_with_http_token` or `authenticate_with_http_token`
    for request authentication. (CVE-2021-22904)

  - Action Pack is a framework for handling and responding to web requests. Under certain circumstances
    response bodies will not be closed. In the event a response is *not* notified of a `close`,
    `ActionDispatch::Executor` will not know to reset thread local state for the next request. This can lead
    to data being leaked to subsequent requests.This has been fixed in Rails 7.0.2.1, 6.1.4.5, 6.0.4.5, and
    5.2.6.1. Upgrading is highly recommended, but to work around this problem a middleware described in GHSA-
    wh98-p28r-vrc9 can be used. (CVE-2022-23633)

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