    Several security vulnerabilities were found in GLib, a general-purpose utility     library, used by projects such as GTK+, GIMP, and GNOME.

    CVE-2023-29499

        GVariant deserialization fails to validate that the input conforms to the         expected format, leading to denial of service.

    CVE-2023-32611

        GVariant deserialization is vulnerable to a slowdown issue where a crafted         GVariant can cause excessive processing, leading to denial of service.

    CVE-2023-32665

        GVariant deserialization is vulnerable to an exponential blowup issue where         a crafted GVariant can cause excessive processing, leading to denial of         service.


    For Debian 10 buster, these problems have been fixed in version     2.58.3-2+deb10u5.

    We recommend that you upgrade your glib2.0 packages.

    For the detailed security status of glib2.0 please refer to     its security tracker page at:

Tenable has extracted the preceding description block directly from the Debian security advisory.

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

The version of glib2 installed on the remote host is prior to 2.56.1-9. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2025-2767 advisory.

    GLib's GVariant deserialization prior to GLib 2.74.4 failed to validate the input conforms to the expected     format, leading to denial of service. (CVE-2023-29499)

    GLib's GVariant deserialization prior to GLib 2.74.4 is vulnerable to a slowdown issue where a crafted     GVariant can cause excessive processing, leading to denial of service. (CVE-2023-32611)

    GLib's 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)

    GLib's 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)

    GLib's GVariant deserialization prior to GLib 2.74.4 is vulnerable to an exponential blowup issue where a     crafted GVariant can cause excessive processing, leading to denial of service. (CVE-2023-32665)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
