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 is affected by a Heap-based Buffer Overflow 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 contains a heap-based buffer overflow vulnerability in its file parsing functionality. When processing a specially crafted malicious file, the application writes data beyond the allocated heap buffer boundaries, potentially allowing an attacker to overwrite adjacent memory and execute arbitrary code in the context of the current user.

MitigationUsers should avoid opening untrusted or unexpected files in Adobe Bridge until an official patch is released. Organizations should implement file type restrictions and user training to minimize exposure to this vulnerability.

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. Identify Adobe Bridge installation and version
    Locate the Adobe Bridge application on the system. On Windows, check Program Files/Adobe/Adobe Bridge or verify via Add/Remove Programs. On macOS, check /Applications/Adobe Bridge. Note the exact version number displayed in the application or system information.
    Affected if The installed version is less than 15.1.5, or greater than or equal to 16.0 but less than 16.0.3
  2. Compare installed version against affected ranges
    Document the full version string (for example, 15.1.3, 16.0.1, or 16.0.3). Cross-reference this against the two affected ranges: any version below 15.1.5, or any version from 16.0 through 16.0.2 inclusive.
    Affected if The version falls within either range: < 15.1.5 OR (>= 16.0 and < 16.0.3)
  3. Determine if Adobe Bridge file viewing is actively used
    Check whether users on this system have workflow that involves opening, viewing, or processing files through Adobe Bridge. This includes using Bridge to preview image assets, PDF files, or other supported file types.
    Affected if Adobe Bridge is used to open or preview files, as the vulnerability triggers during file parsing operations

A system is affected if Adobe Bridge is installed with a version in the vulnerable ranges and users process files through the application, allowing specially crafted files to trigger the heap overflow during parsing.

Upgrade available Upgrade to 15.1.5 / 16.0.3 or later
Fixed in 15.1.516.0.3
Interim mitigation

Users should avoid opening untrusted or unexpected files in Adobe Bridge until an official patch is released. Organizations should implement file type restrictions and user training to minimize exposure to this vulnerability.

Recommended fix High confidence

Adobe Bridge 15.1.5 (15.x branch) or 16.0.3 (16.x branch)

  1. 1. Close any running instances of Adobe Bridge
  2. 2. Back up any custom presets, settings, or workspaces if desired
  3. 3. Open Adobe Creative Cloud desktop application or navigate to https://creativecloud.adobe.com/
  4. 4. Locate Adobe Bridge in your installed applications
  5. 5. Click Update or Install to get the latest version, OR manually download from https://helpx.adobe.com/download-install.html
  6. 6. Verify the installed version is 15.1.5 or later, OR 16.0.3 or later
  7. 7. Do not open untrusted or unexpected Bridge files received via email or downloaded from untrusted sources
Caveat Adobe updates are typically backward compatible with presets and workflows; minor UI changes may occur
