Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

A dangling pointer vulnerability in Ghostscript's gdev_prn_open_printer_seekable() function allows remote attackers to crash the application. This affects the printer device component of Ghostscript through version 10.02.0 and can be triggered via maliciously crafted PostScript or PDF files processed by Ghostscript.

MitigationUpdate Ghostscript to a version beyond 10.02.0 when available. If immediate patching is not possible, restrict or sanitize user-supplied PostScript/PDF input to prevent exploitation.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify Ghostscript is installed
    Run 'gs --version' or check for ghostscript in package management (dpkg -l | grep ghostscript, rpm -qa | grep ghostscript)
    Affected if Ghostscript is found on the system
  2. Determine installed Ghostscript version
    Execute 'gs --version' and note the version number returned
    Affected if Version is 10.02.0 or lower (e.g., 10.01.x, 10.00.x, 9.xx series)
  3. Confirm printer device availability
    Run 'gs -h' or 'gs -q -dNODISPLAY -- gdevprn' to list available devices; the printer device (gdevprn) is built into Ghostscript by default
    Affected if The printer device component is present in the Ghostscript build
  4. Audit for processing of untrusted PostScript/PDF input
    Review application logs, file upload directories, or document processing workflows that invoke Ghostscript on user-supplied .ps or .pdf files
    Affected if Ghostscript is configured to process untrusted or user-uploaded PostScript/PDF files without sanitization

You are affected if Ghostscript version 10.02.0 or lower is installed AND the printer device component is available AND untrusted PostScript/PDF files can be processed by Ghostscript.

Upgrade available Upgrade to a release after 10.02.0
Interim mitigation

Update Ghostscript to a version beyond 10.02.0 when available. If immediate patching is not possible, restrict or sanitize user-supplied PostScript/PDF input to prevent exploitation.

Recommended fix Moderate confidence

Ghostscript version 10.03.0 or later (the first stable release after 10.02.0 that addresses this Use After Free vulnerability)

  1. Check current Ghostscript version using: gs --version
  2. Upgrade Ghostscript to the latest available version beyond 10.02.0 that includes the security fix for CVE-2023-46751
  3. Verify the upgrade was successful by running: gs --version
  4. Test critical document processing workflows to ensure functionality is not affected
Caveat Minor: Some deprecated printer device options may have been removed; test printer-dependent workflows after upgrade
