"The remote Oracle Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the
ELSA-2024-2528 advisory.

  - 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. 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, 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)
