## Technical details

An out-of-bounds write vulnerability (CWE-787) exists in Adobe Acrobat Reader versions 24.001.30365, 26.001.21651 and earlier. The flaw is triggered when the application improperly handles memory during the processing of a PDF file. An attacker can exploit this by convincing a user to open a specifically crafted malicious file (User Interaction required). Successful exploitation allows for arbitrary code execution in the context of the current user, potentially leading to full system compromise. Adobe has addressed this in advisory APSB26-63.
