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

Use-after-free vulnerability in Adobe Reader and Acrobat allows remote attackers to execute arbitrary code via unspecified vectors. The flaw involves improper memory management where the software attempts to access memory that has already been freed, leading to potential code execution.

MitigationApply vendor patches: Adobe Reader/Acrobat 10.x to 10.1.16, 11.x to 11.0.13, DC Classic to 2015.006.30094, and DC Continuous to 2015.009.20069 or later.

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 PDF product
    Open the application and go to Help > About Adobe Acrobat Reader or About Adobe Acrobat, or on Windows check Programs and Features for installed Adobe products
    Affected if Neither Adobe Reader nor Adobe Acrobat is installed, then not affected
  2. Determine the exact version number
    Note the full version string displayed in the About dialog (for example: 10.1.15, 11.0.12, 15.006.30060, 15.008.20082)
    Affected if Version cannot be determined - manual inspection required
  3. Compare Classic version to affected range
    For Acrobat/Reader 10.x: check if version is 10.0 through 10.1.15. For 11.x: check if version is 11.0.0 through 11.0.12. For DC Classic: check if version is 15.006.30060 through 15.006.30093
    Affected if Version falls within any of these ranges - affected by CVE
  4. Compare Continuous version to affected range
    For DC Continuous track: check if version starts with 15.008.20082 through 15.009.20068
    Affected if Version falls within this range - affected by CVE
  5. Confirm product type for DC versions
    On Windows, check the installation path: DC Continuous typically installs under Program Files/Adobe/Acrobat DC/ while DC Classic uses Program Files/Adobe/Acrobat 2015/
    Affected if Cannot distinguish - both DC tracks should be checked against their respective ranges

User is affected if Adobe Acrobat or Reader is installed AND the installed version matches any of the listed vulnerable ranges (10.0-10.1.15, 11.0.0-11.0.12, 15.006.30060-15.006.30093, or 15.008.20082-15.009.20068)

Interim mitigation

Apply vendor patches: Adobe Reader/Acrobat 10.x to 10.1.16, 11.x to 11.0.13, DC Classic to 2015.006.30094, and DC Continuous to 2015.009.20069 or later.

Recommended fix High confidence

Acrobat/Reader 10.1.16+, 11.0.13+, DC Classic 2015.006.30094+, or DC Continuous 2015.009.20069+

  1. 1. Check current Adobe Acrobat or Reader version by opening the application and navigating to Help > About Adobe Acrobat/Reader
  2. 2. Identify which product line and version you have (Acrobat/Reader, Classic/DC Continuous, version number)
  3. 3. For Acrobat/Reader 10.x: Upgrade to version 10.1.16 or later
  4. 4. For Acrobat/Reader 11.x: Upgrade to version 11.0.13 or later
  5. 5. For Acrobat/Reader DC Classic: Upgrade to version 2015.006.30094 or later
  6. 6. For Acrobat/Reader DC Continuous: Upgrade to version 2015.009.20069 or later
  7. 7. Download the appropriate updated version from the official Adobe website at https://get.adobe.com/reader/ or https://get.adobe.com/acrobat/
  8. 8. Close all Adobe applications before running the installer
Caveat Standard upgrade risk - ensure backups of PDF files and custom settings exist before updating
