CVE-2023-42075
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 · uneditedPDF-XChange Editor JPG File Parsing Use-After-Free Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of PDF-XChange Editor. 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 JPG files. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-21691.
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 confidenceA use-after-free vulnerability exists in PDF-XChange Editor's JPG file parsing routine. The software fails to validate the existence of an object before performing operations on it, allowing an attacker to manipulate memory after an object has been freed. This can be leveraged to achieve arbitrary code execution in the context of the current process when a user opens a malicious JPG file.

dbcve checksWork through these to decide whether this CVE applies to you.
-
Check if PDF-XChange Editor is installedOpen the application or check the installed programs list in Windows Control Panel under Programs and FeaturesAffected if PDF-XChange Editor appears in the installed programs list
-
Determine the installed version of PDF-XChange EditorIn the application, go to Help > About PDF-XChange Editor, or right-click the executable in Program Files and select Properties > Details to view the File VersionAffected if The version displayed is 10.0.1.371

Check if PDF-XChange PDF Tools is installedCheck Program Files for the PDF-Tools folder or review installed programs for 'PDF-XChange PDF Tools'Affected if PDF-XChange PDF Tools version 10.0.1.371 is installed
-
Verify the JPG parsing component versionLocate the main executable (PDFXEdit.exe or PDFTools.exe) and check its version property in the file properties dialogAffected if The executable file version matches 10.0.1.371
You are affected if PDF-XChange Editor or PDF-XChange PDF Tools version 10.0.1.371 is installed and you open untrusted JPG files with the software.
