Technical details

A stack-based buffer overflow vulnerability (CWE-121) exists in Adobe Acrobat Reader versions 24.001.30365, 26.001.21651 and earlier. The flaw is triggered when the application improperly handles memory while processing a specially crafted PDF file. An attacker can exploit this by convincing a user to open a malicious document, leading to arbitrary code execution in the context of the current user. The attack vector is local, requiring user interaction (UI:R) but no prior privileges (PR:N). Adobe has addressed this in security bulletin APSB26-63.
