CVE-2023-42100
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 · uneditedKofax Power PDF PDF File Parsing Out-Of-Bounds Read Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Kofax Power PDF. 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 PDF files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated object. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process. . Was ZDI-CAN-21604.

dbcve analysis · high confidenceCVE-2023-42100 is an out-of-bounds read vulnerability in Kofax Power PDF's PDF file parsing functionality. The flaw exists due to insufficient validation of user-supplied data during PDF parsing, allowing an attacker to read past the end of an allocated memory object. While primarily an information disclosure vulnerability, it can be chained with other vulnerabilities to achieve arbitrary code execution in the current process context.

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 Power PDF installationLocate the Power PDF application on the system. Check the installed version through the application's About dialog, or check the program version in Windows Add/Remove Programs, or look for version information in the executable properties of the Power PDF installation directory.Affected if Power PDF is installed and the version is below 5.0.0.12
-
Confirm PDF parsing is in useThis vulnerability affects the PDF file parsing functionality within Power PDF. Any use of Power PDF to open, view, or process PDF files triggers the affected parsing code path.Affected if Power PDF is used to open or process any PDF file, including files from untrusted sources
-
Compare version against vulnerable rangeThe affected version range is any installation of Tungstenautomation Power PDF with version number less than 5.0.0.12. Compare your installed version to this threshold.Affected if The installed version is lower than 5.0.0.12
You are affected if Power PDF is installed with a version below 5.0.0.12 and you use it to open or process PDF files, particularly from untrusted sources.

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.
dbcve · scoped5.0.0.12
Apply vendor-provided patches for Kofax Power PDF when available, and educate users to avoid opening untrusted PDF files from unknown sources.
Power PDF 5.0.0.12
- 1. Verify the currently installed version of Power PDF by opening the application and checking About or Help menu
- 2. Navigate to the official Kofax support website or trusted software distribution channel
- 3. Download Power PDF version 5.0.0.12 or later
- 4. Close all instances of Power PDF and any related processes
- 5. Run the installer and follow the on-screen prompts to complete the upgrade
- 6. After installation, verify the new version by checking Help > About Power PDF
- 7. Test that PDF files open and function correctly after the upgrade
