The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:1804 advisory.

    X.Org is an open-source implementation of the X Window System. It provides the basic low-level     functionality that full-fledged graphical user interfaces are designed upon.

    Mesa provides a 3D graphics API that is compatible with Open Graphics Library (OpenGL). It also provides     hardware-accelerated drivers for many popular graphics chips.

    The following packages have been upgraded to a later upstream version: egl-wayland (1.1.5), libdrm     (2.4.103), libglvnd (1.3.2), libinput (1.16.3), libwacom (1.6), mesa (20.3.3), xorg-x11-server (1.20.10).
    (BZ#1878160, BZ#1886648, BZ#1887654, BZ#1887655)
