"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2025:0077 advisory.

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

    CVE-2023-46751:
    An issue was discovered in the function gdev_prn_open_printer_seekable() in Artifex Ghostscript through
    10.02.0 allows remote attackers to crash the application via a dangling pointer.

    CVE-2024-46951:
    An issue was discovered in psi/zcolor.c in Artifex Ghostscript before 10.04.0. An unchecked Implementation
    pointer in Pattern color space could lead to arbitrary code execution.

    CVE-2024-46952:
    An issue was discovered in pdf/pdf_xref.c in Artifex Ghostscript before 10.04.0. There is a buffer
    overflow during handling of a PDF XRef stream (related to W array values).

    CVE-2024-46953:
    An issue was discovered in base/gsdevice.c in Artifex Ghostscript before 10.04.0. An integer overflow when
    parsing the filename format string (for the output filename) results in path truncation, and possible path
    traversal and code execution.

    CVE-2024-46954:
    An issue was discovered in decode_utf8 in base/gp_utf8.c in Artifex Ghostscript before 10.04.0. Overlong
    UTF-8 encoding leads to possible ../ directory traversal.

    CVE-2024-46956:
    An issue was discovered in psi/zfile.c in Artifex Ghostscript before 10.04.0. Out-of-bounds data access in
    filenameforall can lead to arbitrary code execution.

    CVE-2025-27832:
    An issue was discovered in Artifex Ghostscript before 10.05.0. The NPDL device has a Compression buffer
    overflow for contrib/japanese/gdevnpdl.c.
