Panasonic FPWIN Pro SelectFCS Array Indexing Out-Of-Bounds Write Remote Code Execution Vulnerability

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 SelectFCS method due to improper index calculation for array access. An attacker can leverage this vulnerability to attain code execution under the context of the current process.
