"The remote Fedora 37 host has a package installed that is affected by multiple vulnerabilities as referenced in the
FEDORA-2023-1a7e2b3dda advisory.

  - A flaw was found in GLib. GVariant deserialization is vulnerable to an exponential blowup issue where a
    crafted GVariant can cause excessive processing, leading to denial of service. (CVE-2023-32665)

  - A flaw was found in GLib. GVariant deserialization fails to validate that the input conforms to the
    expected format, leading to denial of service. (CVE-2023-29499)

  - A flaw was found in GLib. GVariant deserialization is vulnerable to a slowdown issue where a crafted
    GVariant can cause excessive processing, leading to denial of service. (CVE-2023-32611)

  - A flaw was found in GLib. The GVariant deserialization code is vulnerable to a heap buffer overflow
    introduced by the fix for CVE-2023-32665. This bug does not affect any released version of GLib, but does
    affect GLib distributors who followed the guidance of GLib developers to backport the initial fix for
    CVE-2023-32665. (CVE-2023-32643)

  - A flaw was found in glib, where the gvariant deserialization code is vulnerable to a denial of service
    introduced by additional input validation added to resolve CVE-2023-29499. The offset table validation may
    be very slow. This bug does not affect any released version of glib but does affect glib distributors who
    followed the guidance of glib developers to backport the initial fix for CVE-2023-29499. (CVE-2023-32636)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
