Name of the Vulnerable Software and Affected Versions Foxit Reader version 10.0.1.35811

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 processing of XFA templates due to the lack of proper validation of user-supplied data. This can result in a write past the end of an allocated data structure, allowing an attacker to execute code in the context of the current process.

Recommendations For Foxit Reader version 10.0.1.35811, consider disabling the processing of XFA templates as a temporary workaround until a patch is available. Restrict access to potentially malicious pages or 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.
