AI-suggested

  1. Implement strict email and file attachment filtering to detect and block suspicious or unexpected InDesign files, especially from unknown sources.
  2. Educate users on the risks of opening files from untrusted or unexpected sources, emphasizing caution with InDesign documents.
  3. Employ endpoint security solutions capable of detecting anomalous behavior related to file parsing or memory access by InDesign.
  4. Monitor for unusual file access patterns or crashes in InDesign that could indicate exploitation attempts.
  5. Maintain an inventory of Adobe InDesign versions deployed and plan for rapid patching once Adobe releases an official fix.
  6. Consider sandboxing or isolating InDesign usage in virtualized environments to limit potential data exposure.
  7. Use Data Loss Prevention (DLP) tools to monitor and prevent unauthorized exfiltration of sensitive information that could result from memory disclosure.

Description

InDesign Desktop versions 20.4, 19.5.4 and earlier are affected by an out-of-bounds read vulnerability that could lead to disclosure of sensitive memory. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
