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-2023:1849-1 advisory.

  - mod_auth_openidc is an authentication and authorization module for the Apache 2.x HTTP server that     implements the OpenID Connect Relying Party functionality. In versions 2.0.0 through 2.4.13.1, when     `OIDCStripCookies` is set and a crafted cookie supplied, a NULL pointer dereference would occur, resulting     in a segmentation fault. This could be used in a Denial-of-Service attack and thus presents an     availability risk. Version 2.4.13.2 contains a patch for this issue. As a workaround, avoid using     `OIDCStripCookies`. (CVE-2023-28625)
