The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 25.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7745-1 advisory.

    It was discovered that CUPS incorrectly handled authentication types other than Basic. An attacker could     possibly use this issue to bypass authentication. (CVE-2025-58060)

    It was discovered that CUPS incorrectly handled deserialization and validation of printer attributes. An     attacker could possibly use this issue to cause a denial of service. (CVE-2025-58364)

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

    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.(CVE-2025-58364)

The CentOS Linux 8.4 host has packages installed that are affected by a vulnerability as referenced in the TuxCare CENTOS8.4:CLSA-2025:1765463952 advisory.

  - 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.

The remote NewStart CGSL host, running version MAIN 7.02, has cups packages installed that are affected by multiple vulnerabilities:

  - libppd <= 2.1b1 ppdCreatePPDFromIPP2 does not validate or sanitize the IPP attributes when writing them to     a temporary PPD file, allowing the injection of attacker controlled data in the resulting PPD.
    (CVE-2024-47175)

  - CUPS is a standards-based, open-source printing system, and `libppd` can be used for legacy PPD file     support. The `libppd` function `ppdCreatePPDFromIPP2` does not sanitize IPP attributes when creating the     PPD buffer. When used in combination with other functions such as `cfGetPrinterAttributes5`, can result in     user controlled input and ultimately code execution via Foomatic. This vulnerability can be part of an     exploit chain leading to remote code execution (RCE), as described in CVE-2024-47176. (CVE-2024-47175)

  - OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. In     versions 2.4.12 and earlier, when the `AuthType` is set to anything but `Basic`, if the request contains     an `Authorization: Basic ...` header, the password is not checked. This results in authentication bypass.
    Any configuration that allows an `AuthType` that is not `Basic` is affected. Version 2.4.13 fixes the     issue. (CVE-2025-58060)

  - OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. Prior     to version 2.4.15, a client that connects to cupsd but sends slow messages, e.g. only one byte per second,     delays cupsd as a whole, such that it becomes unusable by other clients. This issue has been patched in     version 2.4.15. (CVE-2025-58436)
