CVE-2021-45052
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 out-of-bounds read vulnerability 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 TIF 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 confidenceAdobe Bridge versions 11.1.2 and earlier, and 12.0 and earlier contain an out-of-bounds read vulnerability when parsing malicious TIF files. This memory disclosure vulnerability can leak sensitive memory contents and potentially bypass ASLR mitigation, enabling more sophisticated exploit chains.

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.
-
Verify Adobe Bridge is installedCheck if Adobe Bridge application exists on the system. On Windows, look in Program Files/Adobe; on macOS, check /Applications for Adobe Bridge.appAffected if Adobe Bridge is present on the system
-
Determine the installed Adobe Bridge versionLocate Bridge in your installed applications and view its version information. On Windows, right-click the executable and select Properties > Details; on macOS, right-click Adobe Bridge.app and select Get InfoAffected if Version displayed is 11.1.2 or earlier, or exactly 12.0
-
Compare against affected version rangesCompare the installed version number to the affected ranges: versions 11.1.2 and earlier, or version 12.0 exactly. Versions prior to 11.1.3 (such as 11.1.2, 11.1.1, 11.1.0, etc.) are all affectedAffected if Installed version falls within 11.1.2 or earlier, or is exactly 12.0
-
Confirm TIF file processing contextThis vulnerability triggers when Adobe Bridge parses a maliciously crafted TIF file. Verify if the Bridge application is used to preview or process TIF image files in your workflowAffected if Adobe Bridge is used to open, preview, or process TIF files from any source
If Adobe Bridge version is 11.1.2 or earlier, or exactly 12.0, and the application is used to process TIF files, the environment is vulnerable to this CVE.

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. Until patched, refrain from opening untrusted or unexpected TIF files from untrusted sources.
Adobe Bridge 11.1.3 (or 12.0.1+ for the 12.x release line)
- Close any running Adobe Bridge instances
- Navigate to Adobe's official download page for Adobe Bridge (helpx.adobe.com)
- Download Adobe Bridge version 11.1.3 or later (or version 12.0.1 or later if currently on the 12.x release line)
- Run the installer and follow the prompts to complete the upgrade
- Restart Adobe Bridge after installation to ensure the patch is fully applied
