**Name of the Vulnerable Software and Affected Versions** Foxit PDF Reader version 11.2.1.53537 **Description** This issue allows remote attackers to execute arbitrary code on affected installations. User interaction is required, where the target must visit a malicious page or open a malicious file. The flaw exists within the handling of `Doc` objects due to the lack of validating the existence of an object prior to performing operations on it. An attacker can leverage this to execute code in the context of the current process. It may also lead to information disclosure or remote code execution through potential Use-After-Free or Out-of-Bounds Read vulnerabilities when handling certain JavaScripts, `Doc` objects, or AcroForms. **Recommendations** For Foxit PDF Reader version 11.2.1.53537, consider disabling the handling of `Doc` objects until a patch is available. Restrict access to potentially vulnerable JavaScripts, `Doc` objects, or AcroForms to minimize the risk of exploitation. Avoid opening malicious files or visiting suspicious web pages to reduce the risk of remote code execution. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
