Name of the Vulnerable Software and Affected Versions Foxit Reader version 9.0.1.104

Description This issue allows remote attackers to disclose sensitive information on vulnerable installations. User interaction is required, where the target must visit a malicious page or open a malicious file. The flaw exists within ConvertToPDF x86.dll due to the lack of proper validation of user-supplied data, resulting in a read past the end of an allocated object. An attacker can leverage this, in conjunction with other issues, to execute arbitrary code in the context of the current process.

Recommendations For Foxit Reader version 9.0.1.104, consider disabling the ConvertToPDF x86.dll until a patch is available to prevent exploitation. Restrict access to potentially malicious files or web pages to minimize the risk of sensitive information disclosure.
