Summary
InDesign Desktop versions 21.3, 20.5.3 and earlier are affected by a NULL Pointer Dereference vulnerability that could result in an application denial-of-service. An attacker could exploit this to crash the application, requiring user interaction (opening a malicious file).
Risk Assessment
A user opening a malicious file in InDesign may cause the application to crash, leading to loss of unsaved work and service disruption.
Recommendation
Update InDesign Desktop to the latest available version that contains the fix. Avoid opening files from untrusted sources.
