CVE-2017-3023
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 · uneditedAdobe Acrobat Reader versions 11.0.19 and earlier, 15.006.30280 and earlier, 15.023.20070 and earlier have an exploitable memory corruption vulnerability in the JPEG 2000 code-stream tile functionality. Successful exploitation could lead to arbitrary code execution.
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 confidenceMemory corruption vulnerability in Adobe Acrobat Reader's JPEG 2000 code-stream tile parsing functionality allows attackers to potentially execute arbitrary code via specially crafted PDF files containing malicious JPEG 2000 images.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify Adobe product and versionOpen Adobe Acrobat or Reader, then go to Help > About Adobe Acrobat/Reader to display the exact version number. Alternatively, on Windows, check the registry key HKLM\SOFTWARE\Adobe\Adobe Acrobat\DC\InstallVersion for installed version details.Affected if The displayed version falls within 11.0.19 or earlier, 15.006.30280 or earlier, or 15.023.20070 or earlier.
-
Confirm product typeDetermine whether the installed product is Adobe Acrobat, Adobe Acrobat Reader DC, or Adobe Reader (classic). This is visible in the About dialog title or the application window title bar.Affected if The product is any of the following: Adobe Acrobat <= 11.0.19, Adobe Acrobat DC <= 15.006.30280 or <= 15.023.20070, Adobe Acrobat Reader DC <= 15.006.30280 or <= 15.023.20070, or Adobe Reader <= 11.0.19.
-
Verify JPEG 2000 parsing capabilityAdobe Acrobat and Reader include JPEG 2000 image decoding functionality by default for rendering PDF content. No special configuration is required for the parsing code to be present in the application.Affected if The vulnerable version of Acrobat or Reader is installed and can open PDF files.
You are affected if Adobe Acrobat or Adobe Reader version is 11.0.19 or earlier, 15.006.30280 or earlier, or 15.023.20070 or earlier, and the application can open PDF files containing JPEG 2000 images.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate Adobe Acrobat Reader to versions newer than 11.0.19, 15.006.30280, or 15.023.20070 to patch this vulnerability.
