Use-After-Free RCE in Adobe Acrobat Reader
CVE-2025-54257 is a use-after-free vulnerability in Adobe Acrobat Reader affecting versions 24.001.30254, 20.005.30774, 25.001.20672 and earlier on Windows and macOS. The flaw occurs because Acrobat Reader continues to reference memory after it has been freed while processing certain PDF structures. Cisco Talos reported the issue in the page property functionality of Acrobat Reader 2025.001.20531, where specially crafted JavaScript embedded in a malicious PDF can trigger reuse of a previously freed object. This can cause memory corruption and may allow attacker-controlled data to be accessed or executed, resulting in arbitrary code execution in the context of the current user. Exploitation requires the victim to open the malicious PDF file.
