"The remote NewStart CGSL host, running version MAIN 6.06, has glib2 packages installed that are affected by multiple
vulnerabilities:

  - file_copy_fallback in gio/gfile.c in GNOME GLib 2.15.0 through 2.61.1 does not properly restrict file
    permissions while a copy operation is in progress. Instead, default permissions are used. (CVE-2019-12450)

  - GSocketClient in GNOME GLib through 2.62.4 may occasionally connect directly to a target address instead
    of connecting via a proxy server when configured to do so, because the proxy_addr field is mishandled.
    This bug is timing-dependent and may occur only sporadically depending on network delays. The greatest
    security relevance is in use cases where a proxy is used to help with privacy/anonymity, even though there
    is no technical barrier to a direct connection. NOTE: versions before 2.60 are unaffected. (CVE-2020-6750)

  - Rejected reason: Rejected by upstream. (CVE-2023-24593, CVE-2023-25180)

  - An issue was discovered in GNOME GLib before 2.78.5, and 2.79.x and 2.80.x before 2.80.1. When a GDBus-
    based client subscribes to signals from a trusted system service such as NetworkManager on a shared
    computer, other users of the same computer can send spoofed D-Bus signals that the GDBus-based client will
    wrongly interpret as having been sent by the trusted system service. This could lead to the GDBus-based
    client behaving incorrectly, with an application-dependent impact. (CVE-2024-34397)

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