Adobe Acrobat Pro DC WillSave OCG Use-After-Free Remote Code Execution Vulnerability

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Adobe Acrobat Pro DC. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of OCG objects within the WillSave document action. A specially crafted OCG object referenced inside a WillSave document action can force a dangling pointer to be reused after it has been freed.
