Technical details

This is a use-after-free vulnerability in Adobe Acrobat Reader's memory management. The vulnerability occurs when the application attempts to access memory that has already been freed, which could contain sensitive data. Exploitation requires user interaction—specifically, a victim must be tricked into opening a specially crafted malicious PDF file. The attack vector is local and user-assisted. A successful exploit could lead to information disclosure through memory access, though it does not directly enable code execution. Adobe has released a security patch addressing this issue.
