"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by a vulnerability as referenced in the
ALINUX3-SA-2025:0190 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2025-58364:
    OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. In
    versions 2.4.12 and earlier, an unsafe deserialization and validation of printer attributes causes null
    dereference in the libcups library. This is a remote DoS vulnerability available in local subnet in
    default configurations. It can cause the cups & cups-browsed to crash, on all the machines in local
    network who are listening for printers (so by default for all regular linux machines). On systems where
    the vulnerability CVE-2024-47176 (cups-filters 1.x/cups-browsed 2.x vulnerability) was not fixed, and the
    firewall on the machine does not reject incoming communication to IPP port, and the machine is set to be
    available to public internet, attack vector Network is possible. The current versions of CUPS and cups-
    browsed projects have the attack vector Adjacent in their default configurations. Version 2.4.13
    contains a patch for CVE-2025-58364.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.

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