Name of the Vulnerable Software and Affected Versions: Foxit PDF Reader version 11.0.0.49893 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 the `delay` property, resulting from 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. Recommendations: For Foxit PDF Reader version 11.0.0.49893, consider disabling the handling of the `delay` property as a temporary workaround until a patch is available. Restrict access to malicious pages and files to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
