Descriptions

An issue was discovered in Foxit Reader and PhantomPDF before 9.4 on Windows. They allowed Denial of Service (application crash) via image data, because two bytes are written to the end of the allocated memory without judging whether this will cause corruption.

Se ha descubierto un problema en Foxit Reader y PhantomPDF en versiones anteriores a la 9.4 en Windows. Dichas versiones permitían denegaciones de servicio (cierre inesperado de la aplicación) mediante los datos de imagen, debido a que se escribían dos bytes al final de la memoria asignada sin juzgar si esto conduciría a una corrupción.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Foxit Reader. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within ConvertToPDF_x86.dll. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated object. An attacker can leverage this vulnerability to execute code in the context of the current process.
