AI-suggested
Organizations should implement a multi-layered approach to mitigate this vulnerability. First, monitor Adobe’s official channels for patches or updates addressing CVE-2025-54209 and apply them promptly once available. Until patches are released, restrict the opening of InDesign files from untrusted or unknown sources by enforcing strict email and file-sharing policies. Disable automatic preview or rendering of InDesign files in email clients or file explorers to reduce accidental triggering. Educate users about the risks of opening unsolicited or suspicious files and encourage verification of file origins. Employ endpoint protection solutions with heuristic and behavior-based detection capabilities to identify and block attempts to exploit buffer overflow conditions. Consider sandboxing or running Adobe InDesign in a restricted environment to limit the impact of potential exploitation. Regularly back up critical data and maintain incident response plans to quickly address any compromise resulting from exploitation.
Description
InDesign Desktop versions 20.4, 19.5.4 and earlier are 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.
