"The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2021:1789 advisory.

    GUPnP is an object-oriented open source framework for creating UPnP devices and control points, written in
    C using GObject and libsoup. The GUPnP API is intended to be easy to use, efficient and flexible.

    GSSDP implements resource discovery and announcement over SSDP and is part of gUPnP.

    The following packages have been upgraded to a later upstream version: gssdp (1.0.5), gupnp (1.0.6).
    (BZ#1846589, BZ#1861928)

    Security Fix(es):

    * hostapd: UPnP SUBSCRIBE misbehavior in WPS AP (CVE-2020-12695)
