This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Foxit Reader 8.2.0.2051. 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 saveAs JavaScript function. The issue results from the lack of proper validation of user-supplied data, which can lead to writing arbitrary files into attacker controlled locations. An attacker can leverage this vulnerability to execute code under the context of the current process. Was ZDI-CAN-4518.

The ConvertToPDF plugin in Foxit Reader before 8.2.1 and PhantomPDF before 8.2.1 on Windows, when the gflags app is enabled, allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted TIFF image. The vulnerability could lead to information disclosure; an attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the current process.
