This vulnerability allows remote attackers to disclose sensitive information on affected installations of Adobe Acrobat 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 the ID parameter in the PDF trailer. By performing actions in JavaScript, an attacker can disclose the base address of AcroForm.api. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process.
