This vulnerability allows remote attackers to disclose sensitive information 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 Reader's PDF parsing. The process does not properly validate user-supplied data which can result in a read past the end of an allocated object. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the current process.
