The version of xorg-x11-server installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-0409 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
