The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has a package installed that is affected by a vulnerability as referenced in the SUSE-SU-2024:0757-1 advisory.

  - mod_auth_openidc is an OpenID Certified authentication and authorization module for the Apache 2.x HTTP     server that implements the OpenID Connect Relying Party functionality. In affected versions missing input     validation on mod_auth_openidc_session_chunks cookie value makes the server vulnerable to a denial of     service (DoS) attack. An internal security audit has been conducted and the reviewers found that if they     manipulated the value of the mod_auth_openidc_session_chunks cookie to a very large integer, like     99999999, the server struggles with the request for a long time and finally gets back with a 500 error.
    Making a few requests of this kind caused our server to become unresponsive. Attackers can craft requests     that would make the server work very hard (and possibly become unresponsive) and/or crash with minimal     effort. This issue has been addressed in version 2.4.15.2. Users are advised to upgrade. There are no     known workarounds for this vulnerability. (CVE-2024-24814)
