This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Adobe Reader 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 XFA forms. The issue lies in the failure to properly validate user-supplied data which can result in a memory access past the end of an allocated object. An attacker can leverage this vulnerability to execute code under the context of the current process.
