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.

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:0891 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2024-29509:
    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-2024-29506:
    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-2024-29508:
    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-2024-29511:
    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.

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

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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.

The remote Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6897-1 advisory.

    It was discovered that Ghostscript incorrectly handled certain long PDF filter names. An attacker could     possibly use this issue to cause Ghostscript to crash, resulting in a denial of service. This issue only     affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-29506)

    It was discovered that Ghostscript incorrectly handled certain API parameters. An attacker could possibly     use this issue to cause Ghostscript to crash, resulting in a denial of service. This issue only affected     Ubuntu 24.04 LTS. (CVE-2024-29507)

    It was discovered that Ghostscript incorrectly handled certain BaseFont names. An attacker could use this     issue to cause Ghostscript to crash, resulting in a denial of service, or possibly execute arbitrary code.
    (CVE-2024-29508)

    It was discovered that Ghostscript incorrectly handled certain PDF passwords that contained NULL bytes. An     attacker could use this issue to cause Ghostscript to crash, resulting in a denial of service, or possibly     execute arbitrary code. This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-29509)

    It was discovered that Ghostscript incorrectly handled certain certain file paths when doing OCR. An     attacker could use this issue to read arbitrary files and write error messages to arbitrary files. This     issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-29511)

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