Adobe Bridge: Out-of-bounds write leads to arbitrary code execution
Summary
Adobe Bridge contains an out-of-bounds write vulnerability (CWE-787) that can allow arbitrary code execution in the context of the current user. Exploitation requires a victim to open a malicious file, so an attacker would typically need to deliver the file via phishing or a shared download. Adobe is not aware of any exploits in the wild for the issues in this update.
Affected
- Adobe Bridge 16.0.7 and earlier (Windows and macOS)
- Adobe Bridge (LTS) 15.1.8 and earlier (Windows and macOS)
Fixed in
- Adobe Bridge 16.0.8 or later
- Adobe Bridge (LTS) 15.1.9 or later
Workaround
Unknown.
Exploitation
- Adobe is not aware of any exploits in the wild.
- Proof of concept: none found in public sources.
- CISA SSVC: Exploitation none, Automatable no, Technical impact total.
- Requires user interaction (opening a malicious file); local attack vector, no privileges needed.
Our recommendation
- Update Adobe Bridge to 16.0.8 or Bridge (LTS) to 15.1.9 via the Creative Cloud desktop app, the Download Center or the Admin Console.
- Check the Bridge version on all workstations, including installations not managed centrally.
- Treat Bridge files from external senders with caution until patching is complete.
- Monitor for unusual behaviour of Bridge or unexpected processes started by it.
