CVE-2019-13330
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 · uneditedThis vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit Reader 9.5.0.20723. 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 processing of JPG files. The issue results from the lack of proper validation of user-supplied data, which can result in a type confusion condition. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-8742.
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 confidenceType confusion vulnerability in Foxit Reader 9.5.0.20723's JPG file parsing due to lack of proper validation of user-supplied data. Successful exploitation allows remote code execution in the context of the current process via a maliciously crafted JPG file or embedded in a PDF.

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.
-
Verify Foxit Reader installationCheck for Foxit Reader installation by looking in Program Files (C:\Program Files\Foxit Software\Foxit Reader) or searching for foxit.exe in systemAffected if Foxit Reader executable is found on the system
-
Determine installed Foxit Reader versionRight-click foxit.exe, select Properties, then view the Details tab for Product Version, or open Foxit Reader and go to Help > About Foxit ReaderAffected if Version displays as 9.5.0.20723 through 9.6.0.25114 inclusive
-
Confirm version is within affected rangeCompare the identified version number against the affected range: any version less than or equal to 9.6.0.25114 is potentially vulnerableAffected if Installed version is 9.5.0.20723 or any subsequent version up to and including 9.6.0.25114
-
Identify JPG parsing trigger potentialNote that the vulnerability is triggered when opening a maliciously crafted JPG file or a PDF containing a malicious JPG, regardless of JavaScript settingsAffected if User opens untrusted JPG or PDF files with Foxit Reader
If Foxit Reader is installed and its version is 9.5.0.20723 or higher up to 9.6.0.25114, the environment is vulnerable when processing untrusted JPG files.

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 dataApply vendor-supplied patch/update to Foxit Reader; avoid opening untrusted PDF/JPG files and disable JavaScript in Foxit settings to reduce attack surface.
