Adobe Bridge is affected by a critical heap-based buffer overflow vulnerability that could allow an attacker to achieve arbitrary code execution on a user system.

The application is susceptible to a heap-based buffer overflow (CWE-122) triggered when processing malformed files. This vulnerability requires user interaction, as the victim must open a malicious file for the exploit to execute in the context of the current user.

The potential for arbitrary code execution presents a severe risk to organizational security, as it could allow an attacker to gain full control over a compromised workstation. Given the CVSS score of 7.8, this vulnerability is classified as High severity, posing significant threats to data confidentiality, system integrity, and availability. Successful exploitation could lead to unauthorized access to sensitive information or the installation of persistent malware within the internal environment.

Immediate Action: Update Adobe Bridge to the latest version as specified in the official Adobe security advisory APSB25-96.

Proactive Monitoring: Monitor system logs for unusual process execution patterns or abnormal file access attempts originating from Adobe Bridge.

Compensating Controls: Implement endpoint protection solutions with exploit prevention capabilities to detect and block heap-based memory corruption attempts.

Public Exploit Available: No — there is no confirmed public exploit in the available data.

Organizations should prioritize patching Adobe Bridge across all workstations to remediate this heap-based buffer overflow. Given that arbitrary code execution is possible, users should be advised to exercise caution when opening files from untrusted sources until the software has been updated to a secure version.
