Technical details

An out-of-bounds write vulnerability (CWE-787) exists in multiple versions of Adobe Acrobat Reader. The flaw is triggered when the application processes a specially crafted PDF file, leading to memory corruption. An attacker can exploit this by convincing a user to open a malicious document, potentially achieving arbitrary code execution within the security context of the current user. The attack vector is local with a requirement for user interaction (UI:R). Adobe has addressed this issue in security bulletin APSB20-48.
