Multiple buffer overflow vulnerabilities exist when the PLC Editor Version 1.3.5_20190129 processes project files. An attacker could use a specially crafted project file to exploit and execute code under the privileges of the application.
A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
