Name of the Vulnerable Software and Affected Versions: Foxit PhantomPDF version 10.1.0.37527

Description: This issue allows remote attackers to disclose sensitive information 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 handling of U3D objects embedded in PDF files, resulting from the lack of proper validation of user-supplied data. This can lead to a read past the end of an allocated object, potentially allowing an attacker to execute arbitrary code in the context of the current process when combined with other vulnerabilities.

Recommendations: For Foxit PhantomPDF version 10.1.0.37527, consider disabling the handling of U3D objects embedded in PDF files as a temporary workaround until a patch is available. Restrict access to 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.
