SRC-2019-0032 : Foxit Reader PDF Printer Request Out-of-Bounds Read Information Disclosure Vulnerability
This vulnerability allows local attackers to disclose sensitive information on vulnerable installations of Foxit Reader. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the processing of network packet requests. 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 buffer. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges and execute code at medium integrity.
Foxit has issued an update to correct this vulnerability. More details can be found at:
