Name of the Vulnerable Software and Affected Versions Foxit Reader version 9.0.0.29935

Description This issue allows remote attackers to execute arbitrary code on vulnerable 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 record append method, resulting from the lack of proper validation of user-supplied data, leading to a type confusion condition. An attacker can leverage this to execute code under the context of the current process.

Recommendations For Foxit Reader version 9.0.0.29935, consider disabling the handling of the record append method as a temporary workaround until a patch is available. Restrict access to malicious pages or files to minimize the risk of exploitation.
