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 24.001.30225, 20.005.30748, 25.001.20428 and earlier are affected by an out-of-bounds read vulnerability when parsing a crafted file, which could result in a read past the end of an allocated memory structure. An attacker could leverage this vulnerability to execute code 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

Adobe Acrobat Reader contains an out-of-bounds read vulnerability when parsing crafted files, allowing an attacker to read past the end of allocated memory structures. Successful exploitation could enable code execution in the context of the current user, but requires victim interaction (opening a malicious PDF file).

MitigationUpdate Adobe Acrobat Reader to version 24.001.30226 or later for the 24.x branch, 20.005.30749 or later for the 20.x branch, or 25.001.20429 or later for the 25.x branch. Users should avoid opening untrusted PDF files.

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. Locate Adobe Acrobat Reader installation
    Check for acrord32.exe (32-bit) or acrord64.exe (64-bit) in typical locations: C:\Program Files\Adobe\Acrobat Reader <version>\ or C:\Program Files (x86)\Adobe\Acrobat Reader <version>\
    Affected if Adobe Acrobat Reader is installed on the system
  2. Determine installed version number
    Right-click the Acrobat Reader executable, select Properties, and view the Details tab for the Product Version field. Alternatively, open Adobe Acrobat Reader and navigate to Help > About Adobe Acrobat Reader to display the exact version number.
    Affected if The displayed version falls within any of these ranges: 20.001.30002 through 20.005.30762, 24.0.0 through 24.001.30234, or 15.008.20082 through 25.001.20431
  3. Verify product variant
    Confirm whether the installation is standard Adobe Acrobat Reader or Adobe Acrobat Reader DC by checking the installation folder name and the executable filename (acrord32.exe/acrord64.exe vs Reader/ folder naming)
    Affected if The product is Adobe Acrobat Reader or Adobe Acrobat Reader Dc with a version matching the affected ranges above

A user is affected if Adobe Acrobat Reader (or Reader Dc) is installed with a version matching >= 20.001.30002 but < 20.005.30763, >= 24.0.0 but < 24.001.30235, or >= 15.008.20082 but < 25.001.20432.

  5. 5. Alternatively, manually download the latest version from the official Adobe website: https://get.adobe.com/reader/ (for Reader) or https://get.adobe.com/acrobat/ (for Acrobat)
  6. 6. Restart the application after installation
  7. 7. Verify the installed version matches or exceeds the fixed version: 20.005.30763 (for version 20.x), 24.001.30235 (for version 24.x), or 25.001.20432 (for version 25.x)
Caveat Standard minor version upgrades typically have no breaking changes; however, review release notes for any feature modifications or system requirements changes
