"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2024:0225 advisory.

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

    CVE-2024-47076:
    CUPS is a standards-based, open-source printing system, and `libcupsfilters` contains the code of the
    filters of the former `cups-filters` package as library functions to be used for the data format
    conversion tasks needed in Printer Applications. The `cfGetPrinterAttributes5` function in
    `libcupsfilters` does not sanitize IPP attributes returned from an IPP server. When these IPP attributes
    are used, for instance, to generate a PPD file, this can lead to attacker controlled data to be provided
    to the rest of the CUPS system.

    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-2024-47176:
    CUPS is a standards-based, open-source printing system, and `cups-browsed` contains network printing
    functionality including, but not limited to, auto-discovering print services and shared printers. `cups-
    browsed` binds to `INADDR_ANY:631`, causing it to trust any packet from any source, and can cause the
    `Get-Printer-Attributes` IPP request to an attacker controlled URL. When combined with other
    vulnerabilities, such as CVE-2024-47076, CVE-2024-47175, and CVE-2024-47177, an attacker can execute
    arbitrary commands remotely on the target machine without authentication when a malicious printer is
    printed to.

    CVE-2024-47850:
    CUPS cups-browsed before 2.5b1 will send an HTTP POST request to an arbitrary destination and port in
    response to a single IPP UDP packet requesting a printer to be added, a different vulnerability than
    CVE-2024-47176. (The request is meant to probe the new printer but can be used to create DDoS
    amplification attacks.)
