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
Acrobat Reader versions 20.005.30636, 24.002.20965, 24.002.20964, 24.001.30123 and earlier are affected by a Use After Free vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

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 Use After Free vulnerability in Adobe Acrobat Reader allows arbitrary code execution when a victim opens a specially crafted malicious PDF file. The vulnerability exploits memory that has been freed but still referenced, potentially allowing an attacker to control execution flow.

MitigationUpdate Adobe Acrobat Reader to the latest patched version and exercise caution when opening PDF files from untrusted sources.

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. Check if Adobe Acrobat Reader is installed
    On Windows, open Registry Editor and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Adobe\Adobe Acrobat\Reader\DC\Install or check in Programs and Features. On macOS, check /Applications for Adobe Acrobat Reader.app.
    Affected if Adobe Acrobat Reader or Adobe Acrobat Reader Dc is installed on the system
  2. Determine the installed version on Windows
    Open Registry Editor and go to HKEY_LOCAL_MACHINE\SOFTWARE\Adobe\Adobe Acrobat\Reader\DC\Install, then look for the Version value. Alternatively, open Adobe Acrobat Reader, go to Help > About Adobe Acrobat Reader.
    Affected if The version displayed is in the affected ranges: 20.001.3005 to 20.005.30655 (inclusive), or 24.002.20964 to 24.002.21004 (inclusive) for Reader Dc
  3. Determine the installed version on macOS
    Right-click on Adobe Acrobat Reader.app in /Applications, select Get Info, and look at the Version field under General.
    Affected if The version displayed falls within the affected ranges listed above
  4. Verify if Acrobat (not Reader) is installed
    Check for Adobe Acrobat (not Reader) installation using the same methods, looking at the version in the same registry locations or via Help > About.
    Affected if Adobe Acrobat or Adobe Acrobat Dc is installed with a version in the ranges: 20.001.3005 to 20.005.30655, 24.001.20604 to 24.001.30158, or 24.002.20964 to 24.002.21004

You are affected if Adobe Acrobat Reader, Adobe Acrobat Reader Dc, Adobe Acrobat, or Adobe Acrobat Dc is installed with a version matching any of the listed affected ranges.
