Technical details
The vulnerability is an integer overflow or wraparound condition in Acrobat Reader's PDF parsing engine. The flaw exists in a memory handling component that processes crafted PDF structures, allowing an attacker to bypass bounds checks and corrupt memory. The attack requires user interaction—a victim must open a malicious PDF file. Successful exploitation grants arbitrary code execution with the privileges of the logged-in user. No evidence of active exploitation in the wild has been reported. Adobe has released patches through bulletin APSB26-141.
