Out-of-bounds read vulnerability exists in Kostac PLC Programming Software (Former name: Koyo PLC Programming Software) Version 1.6.9.0 and earlier. When processing a comment block in stage information, the end of data cannot be verified and out-of-bounds read occurs. As a result, opening a specially crafted project file may lead to information disclosure and/or arbitrary code execution.
The product reads data past the end, or before the beginning, of the intended buffer.
