Name of the Vulnerable Software and Affected Versions Foxit PhantomPDF version 9.2.0.9297

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 conversion of HTML files to PDF, resulting from the lack of proper validation of user-supplied data. This can lead to a write past the end of an allocated structure, allowing an attacker to execute code in the context of the current process.
