CVE-2018-5676: Buffer Overflow
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Foxit Reader before 9.1 and PhantomPDF before 9.1. 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 processing of specially crafted pdf files with embedded u3d images. Crafted data in the PDF file can trigger an overflow of a heap-based buffer. An attacker can leverage this vulnerability to execute code under the context of the current process, a different vulnerability than CVE-2018-5674 and CVE-2018-5678.
