CVE-2021-27261: Foxit PhantomPDF U3D File Parsing Out-Of-Bounds Read Remote Code Execution Vulnerability
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PhantomPDF 10.1.0.37527. 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 U3D objects in PDF files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated structure. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-12269.
