Medium Nessus Plugin ID 121046


A PDF viewer installed on the remote Windows host is affected by multiple vulnerabilities.


The version of Foxit Reader installed on the remote Windows host is prior to 9.4. It is, therefore, affected by multiple vulnerabilities:

- An out-of-bounds read/write vulnerability and crash when handling XFA element attributes. (CVE-2018-3956)

- A signature validation bypass vulnerability which could lead to incorrect validation results.
(CVE-2018-18688, CVE-2018-18689)

- Flaws in how PDF files are processed/handled could lead to arbitrary code execution. An attacker can exploit this by convincing a user to open a specially crafted file in order to cause the execution of arbitrary code. (CVE-2019-6728,CVE-2019-6729)

Additionally, the application was affected by multiple potential information disclosure, denial of service, and remote code execution vulnerabilities.
