This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Panasonic FPWIN Pro. 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 processing of a project file. A specially-crafted project file will lead to a write beyond the end of a heap buffer in the GetBlock method of the HEAPSTREAM object. An attacker can leverage this vulnerability to attain code execution under the context of the current process.
