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
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PDF Reader 11.1.0.52543. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of JP2 images. Crafted data in a JP2 image can trigger a read past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-16186.

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

Foxit PDF Reader 11.1.0.52543 contains an out-of-bounds read vulnerability in its JP2 image parser. By crafting malicious JP2 image data embedded in a PDF file or web page, an attacker can read beyond the bounds of an allocated buffer, potentially achieving arbitrary code execution within the context of the current process.

MitigationUpdate Foxit PDF Reader to the latest patched version. Avoid opening untrusted PDF files or visiting malicious web pages that could deliver specially crafted JP2 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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Foxit PDF Reader installation
    Open Windows Settings > Apps > Installed Apps (or Programs and Features in Control Panel) and search for 'Foxit Reader' or 'Foxit PDF Reader'. Alternatively, check common installation paths like C:\Program Files\Foxit Software\Foxit Reader or C:\Program Files (x86)\Foxit Software\Foxit Reader.
    Affected if Foxit PDF Reader appears in the installed programs list.
  2. Identify installed Foxit version
    Launch Foxit PDF Reader, then go to Help > About Foxit Reader (or press F9). The version number will be displayed in the dialog box. Alternatively, right-click the Foxit Reader shortcut, select Properties, and check the Details tab for the product version.
    Affected if The version number is less than 11.2.1 (for example, 11.1.0.52543 or earlier, or any version 10.x.x).
  3. Verify JP2 image parsing capability
    The JP2 (JPEG 2000) image parser is a built-in component of Foxit PDF Reader and activates automatically when opening PDF files containing JP2 images. There is no separate enable/disable toggle for this feature in standard configurations.
    Affected if The JP2 parser is present in all standard Foxit PDF Reader installations and activates upon opening a PDF file containing JP2 image data.
  4. Inspect PDF files for JP2 image content
    Open PDF files in Foxit PDF Reader, then use the Navigation Pane (Ctrl+6) to view embedded images, or use File > Properties > Description to examine the document. You can also check using command-line tools like pdfinfo (from XPDF) or similar utilities to identify if a PDF contains JP2/JPEG2000 streams.
    Affected if The user has PDF files that contain embedded JP2 (JPEG 2000) images.

A user is affected if Foxit PDF Reader version is below 11.2.1 and they open PDF files or view web pages containing specially crafted JP2 image data that triggers the out-of-bounds read vulnerability.
