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
Bridge versions 15.1.3, 16.0.1 and earlier are affected by an Integer Overflow or Wraparound vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

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

Adobe Bridge versions 15.1.3, 16.0.1 and earlier contain an integer overflow vulnerability during file parsing. When a user opens a specially crafted malicious file, the integer overflow can be triggered, leading to arbitrary code execution in the context of the current user session.

MitigationUpdate Adobe Bridge to a patched version once released. Until then, instruct users to avoid opening files from untrusted sources and consider deploying additional file filtering or sandboxing controls.

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 Adobe Bridge is installed
    Locate Adobe Bridge on the system by checking installed applications in Windows Settings or the Add/Remove Programs list, or by searching for the Bridge.exe executable in typical Adobe installation directories
    Affected if Adobe Bridge application is found on the system
  2. Retrieve the installed version number
    Right-click on the Adobe Bridge executable or shortcut, select Properties, and view the Details tab to find the File Version, or open Bridge and navigate to Help > About Adobe Bridge to display the version
    Affected if Version number cannot be determined or is not visible
  3. Compare version to affected ranges
    Check if the installed version is less than 15.1.4, or falls within the 16.0.0 to 16.0.1 range. Safe versions are 15.1.4 and later, or 16.0.2 and later
    Affected if Installed version is 15.1.3 or earlier, OR is 16.0.0 or 16.0.1

The environment is affected if the installed Adobe Bridge version is either below 15.1.4 or between 16.0.0 and 16.0.1 inclusive, since the integer overflow vulnerability exists in these version ranges.
