"According to the versions of the glib2 package installed, the EulerOS installation on the remote host is affected by the
following vulnerabilities :

    A flaw was found in GLib. An integer overflow and buffer under-read occur when parsing a long invalid ISO
    8601 timestamp with the g_date_time_new_from_iso8601() function.(CVE-2025-3360)

    A vulnerability was found in GNU GLib up to 2.84.0 on Windows (Software Library). It has been rated as
    problematic. Affected by this issue is some unknown processing of the component Command Line Handler.
    Upgrading to version 2.84.1 eliminates this vulnerability.(CVE-2025-4056)

Tenable has extracted the preceding description block directly from the EulerOS glib2 security advisory.

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