"It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2024-692 advisory.

    Artifex Ghostscript before 10.03.0 has a stack-based buffer overflow in the pdfi_apply_filter() function
    via a long PDF filter name. (CVE-2024-29506)

    Artifex Ghostscript before 10.03.0 sometimes has a stack-based buffer overflow via the CIDFSubstPath and
    CIDFSubstFont parameters. (CVE-2024-29507)

    Artifex Ghostscript before 10.03.0 has a heap-based pointer disclosure (observable in a constructed
    BaseFont name) in the function pdf_base_font_alloc. (CVE-2024-29508)

    Artifex Ghostscript before 10.03.0 has a heap-based overflow when PDFPassword (e.g., for runpdf) has a
    \000 byte in the middle. (CVE-2024-29509)

    Artifex Ghostscript before 10.03.1, when Tesseract is used for OCR, has a directory traversal issue that
    allows arbitrary file reading (and writing of error messages to arbitrary files) via OCRLanguage. For
    example, exploitation can use debug_file /tmp/out and user_patterns_file /etc/passwd. (CVE-2024-29511)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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