A buffer overflow vulnerability exists in PDF Shaper versions 3.5 and 3.6 when converting a crafted PDF file to an image using the 'Convert PDF to Image' functionality. An attacker can exploit this vulnerability by tricking a user into opening a maliciously crafted PDF file, leading to arbitrary code execution under the context of the user. This vulnerability has been verified on Windows XP, 7, 8, and 10 platforms using the PDFTools.exe component.
