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 the handling of Font streams. A crafted Font stream can trigger a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process.
