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
Integer overflow in Adobe Reader and Acrobat 10.x before 10.1.13 and 11.x before 11.0.10 on Windows and OS X allows attackers to execute arbitrary code via unspecified vectors.

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

Integer overflow vulnerability in Adobe Reader and Acrobat 10.x before 10.1.13 and 11.x before 11.0.10 allows remote attackers to execute arbitrary code via unspecified vectors. The overflow occurs when the software processes maliciously crafted files, causing memory corruption that can be leveraged for code execution.

MitigationUpdate Adobe Reader and Acrobat to version 10.1.13 or later (for 10.x) and 11.0.10 or later (for 11.x) on Windows and OS X systems. Apply the vendor patch immediately given the CVSS 10 severity and public disclosure.

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 installed Adobe products
    Check for Adobe Acrobat or Adobe Reader installation. On Windows, check Add/Remove Programs or look in C:\Program Files\Adobe\. On Mac, check /Applications for Adobe Acrobat or Adobe Reader apps.
    Affected if Adobe Acrobat or Adobe Reader is installed on the system
  2. Determine Adobe Reader version
    Open Adobe Reader, then go to Help > About Adobe Reader to display the version number.
    Affected if Version is 10.0, 10.0.1, 10.0.2, 10.0.3, 10.1, 10.1.1, 10.1.2, 10.1.3, 10.1.4, 10.1.5, 10.1.6, or 10.1.7
  3. Determine Adobe Acrobat version
    Open Adobe Acrobat, then go to Help > About Adobe Acrobat to display the version number.
    Affected if Version is 10.0, 10.0.1, 10.0.2, 10.0.3, 10.1, 10.1.1, 10.1.2, 10.1.3, 10.1.4, 10.1.5, 10.1.6, or 10.1.7
  4. Verify file processing exposure
    Confirm whether the system routinely opens PDF files from external or untrusted sources, as exploitation requires processing a maliciously crafted PDF file.
    Affected if Users open PDF files from external or untrusted sources on a vulnerable version

The system is affected if Adobe Acrobat or Adobe Reader version 10.0 through 10.1.7 is installed and processes PDF files from external or untrusted sources.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update Adobe Reader and Acrobat to version 10.1.13 or later (for 10.x) and 11.0.10 or later (for 11.x) on Windows and OS X systems. Apply the vendor patch immediately given the CVSS 10 severity and public disclosure.

Recommended fix High confidence

Adobe Reader/Acrobat 10.1.13+ or 11.0.10+ (latest available version recommended)

  1. 1. Identify the currently installed Adobe Reader or Acrobat version by opening the application and navigating to Help > About Adobe Reader/Acrobat
  2. 2. For Adobe Reader 10.x users: Upgrade to version 10.1.13 or later
  3. 3. For Adobe Acrobat 10.x users: Upgrade to version 10.1.13 or later
  4. 4. For Adobe Reader 11.x users: Upgrade to version 11.0.10 or later
  5. 5. For Adobe Acrobat 11.x users: Upgrade to version 11.0.10 or later
  6. 6. Download the appropriate fixed version from the official Adobe website (helpx.adobe.com)
  7. 7. Install the update and restart the application
Caveat Large version jumps may require accepting new license terms or reconfiguration of preferences
