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 layout elements due to the lack of proper validation of user-supplied data, resulting in 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 layout elements as a temporary workaround until a patch is available. Restrict access to potentially malicious pages or files to minimize the risk of exploitation.
