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
Adobe Acrobat Reader versions 23.006.20360 (and earlier) and 20.005.30524 (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.

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. Confirm Adobe Acrobat installation
    Check for Adobe Acrobat or Adobe Acrobat Reader in the system. On Windows, look in Control Panel > Programs and Features, or check C:\Program Files\Adobe or C:\Program Files (x86)\Adobe for Acrobat.exe or AcroRd32.exe files.
    Affected if Adobe Acrobat or Adobe Acrobat Reader is installed on the system
  2. Identify installed product version
    Open Adobe Acrobat or Reader, then go to Help > About Adobe Acrobat (or About Adobe Reader). Alternatively, on Windows, check the version in the registry key HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{AC76BA86-7AD7-xxxx-xxxx-xxxxxxxxxxxx} or view the version property of the executable file.
    Affected if A version number is displayed or found in the registry
  3. Compare against vulnerable version ranges
    Match the identified version to the affected ranges: for Continuous (DC) versions, check if version is >= 15.008.20082 and < 23.006.20380; for 20.x versions, check if version is >= 20.001.30005 and < 20.005.30539.
    Affected if The installed version falls within any of the affected ranges: 15.008.20082 to 23.006.20380 (DC/Reader DC) or 20.001.30005 to 20.005.30539 (20.x/Reader 20.x)

If Adobe Acrobat or Adobe Acrobat Reader is installed and its version falls within 15.008.20082-23.006.20380 (DC/Reader DC) or 20.001.30005-20.005.30539 (20.x/Reader 20.x), the environment is vulnerable to CVE-2023-44367.
