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 that could lead to disclosure of sensitive memory. An attacker could leverage this vulnerability to bypass mitigations such as ASLR. 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. Identify the installed Adobe product
    Open Adobe Acrobat Reader or Acrobat, go to Help > About Adobe Acrobat Reader (or About Adobe Acrobat). Note whether the product is Acrobat or Reader, and whether it is the 'Dc' (Document Cloud) variant.
    Affected if The product is Adobe Acrobat Reader or Adobe Acrobat (or their Dc variants)
  2. Determine the installed version number
    In the About dialog, record the exact version number displayed (for example: 24.001.30200 or 20.001.30025).
    Affected if A version number is displayed showing the installed build
  3. Compare against affected version ranges
    Check if the installed version falls within any of these vulnerable ranges: Acrobat 20.x: 20.001.30002 through 20.005.30762; Acrobat 24.x: 24.0.0 through 24.001.30234; Acrobat Dc / Reader Dc 15.x+: 15.008.20082 through 25.001.20431.
    Affected if The installed version is within any of these ranges: 20.001.30002 to 20.005.30762, 24.0.0 to 24.001.30234, or 15.008.20082 to 25.001.20431 (note: the exact upper bound depends on the product line)
  4. Confirm product is configured to open PDF files
    Verify that Adobe Acrobat Reader or Acrobat is set as the default handler for PDF files, or that users commonly open PDF attachments from this installation.
    Affected if The software is used to open PDF files in the environment

The environment is affected if Adobe Acrobat Reader or Acrobat (including Dc variants) is installed with a version matching the affected ranges and the software is used to open PDF documents.
