AI-suggested
1. Monitor Adobe’s official channels for security updates and apply patches immediately once available. 2. Until patches are released, implement strict file handling policies: restrict opening InDesign files from untrusted or unknown sources. 3. Employ endpoint protection solutions capable of detecting anomalous behavior related to memory corruption or code execution. 4. Educate users on the risks of opening unsolicited or suspicious files, emphasizing caution with email attachments and downloads. 5. Use application whitelisting and sandboxing technologies to limit the impact of potential exploitation. 6. Regularly back up critical design files and maintain offline copies to ensure recovery in case of compromise. 7. Consider network segmentation to isolate workstations running InDesign from sensitive or critical infrastructure to reduce lateral movement risk.
Description
InDesign Desktop versions ID20.2, ID19.5.3 and earlier are affected by an out-of-bounds write 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.
