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, 24.002.20964, 24.001.30123, 24.002.20991 and earlier are affected by a Use After Free 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.

dbcve analysis · high confidence

A Use After Free vulnerability in Adobe Acrobat Reader allows an attacker to read sensitive memory contents after a memory region has been freed. This memory disclosure can be leveraged to defeat ASLR by leaking memory addresses. Exploitation requires a victim to open a specially crafted malicious PDF file.

MitigationUpdate Adobe Acrobat Reader to the latest version beyond 24.002.20991. Additionally, enforce least-privilege execution and educate users to avoid 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. Verify Adobe Acrobat Reader is installed
    Check the Windows registry key HKEY_LOCAL_MACHINE\SOFTWARE\Adobe\Acrobat Reader\DC\InstallPath or look for the executable (AcroRd32.exe or AcroRd64.exe) in Program Files or Program Files (x86) directories.
    Affected if Adobe Acrobat Reader is present on the system.
  2. Determine the installed version
    Open the executable properties of AcroRd32.exe or AcroRd64.exe and read the File Version field, or query the registry value at HKEY_LOCAL_MACHINE\SOFTWARE\Adobe\Acrobat Reader\DC\InstallVersion.
    Affected if The version cannot be determined or the product is not found.
  3. Compare version to affected ranges
    Compare the installed version against the following vulnerable ranges: 20.001.30005 through 20.005.30654, and 24.001.20604 through 24.001.30158. For Acrobat Reader DC, also compare to 15.007.20033 through 24.002.21004.
    Affected if The installed version falls within any of these ranges.
  4. Confirm product type and build
    Identify whether the installation is Adobe Acrobat (Standard/Pro) or Adobe Acrobat Reader, and whether it includes DC (Document Cloud) by checking the registry path or executable name.
    Affected if The product matches Adobe Acrobat Reader Dc or Adobe Acrobat Reader with a vulnerable version.
  5. Inspect recent PDF handling behavior
    Review system activity logs or ask users if they have recently opened PDF files from untrusted or unknown sources, as exploitation requires opening a specially crafted malicious PDF.
    Affected if Users have opened untrusted PDF files while running a vulnerable version.

A user is affected if Adobe Acrobat Reader (or Reader DC) is installed with a version matching the ranges 20.001.30005-20.005.30654, 24.001.20604-24.001.30158, or 15.007.20033-24.002.21004.
