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

Description This issue allows remote attackers to execute arbitrary code 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, which can lead to an out-of-bounds read condition. An attacker can leverage this to execute code in the context of the current process.

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.
