Foxit PDF ActiveX before 5.5.1 allows remote code execution via command injection because of the lack of a security permission control.

Foxit Reader before 9.5, and PhantomPDF before 8.3.10 and 9.x before 9.5, has a proxyCPDFAction race condition that can cause a stack-based buffer overflow or an out-of-bounds read.

Foxit Reader before 9.5, and PhantomPDF before 8.3.10 and 9.x before 9.5, has a proxyDoAction race condition that can cause a stack-based buffer overflow or an out-of-bounds read, a different issue than CVE-2018-20310 because of a different opcode.

An issue was discovered in Foxit Reader before 10.1.1 (and before 4.1.1 on macOS) and PhantomPDF before 9.7.5 and 10.x before 10.1.1 (and before 4.1.1 on macOS). An attacker can spoof a certified PDF document via an Evil Annotation Attack because the products fail to consider a null value for a Subtype entry of the Annotation dictionary, in an incremental update.

A type confusion vulnerability exists in the JavaScript engine of Foxit Software’s Foxit PDF Reader, version 10.1.0.37527. A specially crafted PDF document can trigger an improper use of an object, resulting in memory corruption and arbitrary code execution. An attacker needs to trick the user to open the malicious file to trigger this vulnerability. If the browser plugin extension is enabled, visiting a malicious site can also trigger the vulnerability.

A use after free vulnerability exists in the JavaScript engine of Foxit Software’s Foxit PDF Reader, version 10.1.0.37527. A specially crafted PDF document can trigger reuse of previously free memory which can lead to arbitrary code execution. An attacker needs to trick the user to open the malicious file to trigger this vulnerability. If the browser plugin extension is enabled, visiting a malicious site can also trigger the vulnerability.

An issue was discovered in Foxit Reader and PhantomPDF 10.1.0.37527 and earlier. There is a null pointer access/dereference while opening a crafted PDF file, leading the application to crash (denial of service).

Foxit Reader before 10.0 allows Remote Command Execution via the app.opencPDFWebPage JavsScript API. An attacker can execute local files and bypass the security dialog.
