Advantech WebAccess HMI Designer, Versions 2.1.9.31 and prior. Multiple heap-based buffer overflow vulnerabilities may be exploited by opening specially crafted project files that may overflow the heap, which may allow remote code execution, disclosure/modification of information, or cause the application to crash.
A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
The product writes data past the end, or before the beginning, of the intended buffer.
