Technical details

A Use After Free (CWE-416) vulnerability exists in Adobe InDesign Desktop versions 21.3, 20.5.3 and earlier. The flaw occurs when the application continues to use a pointer after it has been freed, which can be leveraged to execute arbitrary code. The attack vector is local, requiring a user to interact with a malicious file (UI:R). If successful, an attacker can achieve code execution with the privileges of the current user, potentially leading to full system compromise. Adobe has addressed this in newer versions; users should refer to APSB26-58 for patching details.
