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
STDU Viewer 1.6.375 allows attackers to execute arbitrary code or cause a denial of service via a crafted .jb2 file, related to "Heap Corruption starting at wow64!Wow64NotifyDebugger+0x000000000000001d."

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 · moderate confidence

STDU Viewer 1.6.375 contains a heap corruption vulnerability when parsing crafted JB2 image files. The heap corruption occurs in the Windows WOW64 layer (wow64!Wow64NotifyDebugger), indicating the vulnerability can be triggered on 64-bit Windows systems. Successful exploitation could allow arbitrary code execution or cause application denial of service.

MitigationAvoid opening untrusted or unknown JB2 files with STDU Viewer. Since STDU Viewer appears to be an older/legacy application with no indicated patch, consider using alternative image viewers or isolated VM environments for viewing JB2 files from untrusted sources.

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 STDU Viewer is installed
    Check for STDU Viewer in installed programs via Control Panel > Programs and Features, or search for stdviewer.exe in common installation paths like C:\Program Files\STDU Viewer or C:\Program Files (x86)\STDU Viewer
    Affected if STDU Viewer version 1.6.375 is present on the system
  2. Verify the exact version number
    Right-click stdviewer.exe, select Properties, then go to the Details tab to view the File Version. Alternatively, run 'wmic product get name,version' or check the application's About/Help menu
    Affected if The version reported is exactly 1.6.375
  3. Check for JB2 file associations
    Search for .jb2 file associations in Windows Explorer: look for .jb2 files on the system, or check HKEY_CLASSES_ROOT\.jb2 in the Windows Registry to see if STDU Viewer is registered as the handler for .jb2 files
    Affected if STDU Viewer is registered as the default handler for .jb2 files and such files can be opened directly with the application
  4. Confirm Windows system architecture
    Open System Properties (win + pause) or run 'systeminfo' in Command Prompt. Look for OS Name and System Type indicating 64-bit Windows (x64-based PC)
    Affected if Running a 64-bit version of Windows, which enables the WOW64 layer where the heap corruption occurs

You are affected if STDU Viewer version 1.6.375 is installed on a 64-bit Windows system and the application can open .jb2 files, as the vulnerability triggers when parsing a crafted JB2 image file.
