CVE-2021-45051
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 · uneditedAdobe Bridge version 11.1.2 (and earlier) and version 12.0 (and earlier) are affected by an use-after-free vulnerability in the processing of Format event actions that could lead to disclosure of sensitive memory. An attacker could leverage this vulnerability to bypass mitigations such as ASLR. 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 · high confidenceAdobe Bridge contains a use-after-free vulnerability in the processing of Format event actions. When a victim opens a specially crafted malicious file, the vulnerability can be triggered, leading to disclosure of sensitive memory contents and enabling bypass of ASLR mitigation. Exploitation requires user interaction in the form of opening the malicious file.

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.
-
Determine installed Adobe Bridge versionOpen Adobe Bridge and navigate to Help > About Adobe Bridge, or right-click the Adobe Bridge executable (Bridge.exe) in the installation directory and select Properties > Details to view the Product VersionAffected if Version shows 12.0 or any 11.x version below 11.1.3 (for example 11.0.0 through 11.1.2)
-
Locate Adobe Bridge installation directoryCommon paths include C:\Program Files\Adobe\Adobe Bridge 2022\ or C:\Program Files\Adobe\Adobe Bridge CC 2021\. Verify the exact folder name matches your installed versionAffected if The installation folder exists and contains Bridge.exe, indicating the software is present
-
Confirm Windows registry version entryOpen Registry Editor and navigate to HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\Bridge.exe, or check HKLM\SOFTWARE\Adobe\Bridge\[version] for the ProductVersion valueAffected if Registry entry shows a version number matching the affected range (< 11.1.3 or = 12.0)
You are affected if Adobe Bridge is installed and its version is either 12.0 exactly or any version in the 11.x branch prior to 11.1.3.

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 · scoped11.1.3
Update Adobe Bridge to the latest patched version (11.1.3 or later for the 11.x branch, 12.0.1 or later for the 12.x branch). Implement application whitelisting and user training to avoid opening untrusted files as an additional defense-in-depth measure.
Adobe Bridge 11.1.3 (for 11.x branch) or Adobe Bridge 12.0.1+ (for 12.x branch)
- 1. Open Adobe Bridge application on your system.
- 2. Go to Help menu and select 'Check for Updates' to see if version 11.1.3 or 12.0.1 is available.
- 3. Alternatively, download the latest Adobe Bridge version from the official Adobe website (get.adobe.com/bridge).
- 4. Install the updated version (11.1.3 for version 11.x users, or 12.0.1+ for version 12.0 users).
- 5. Restart Adobe Bridge after the update completes.
- 6. Verify the installed version by going to Help > About Adobe Bridge to confirm the fix is applied.
