implementations use the "Canaries"-based detection technology to detect such damages.
"Canaries" probe:
To detect the damage to the function stack, You need to modify the structure of the function stack and insert a canary word between the buffer zone and control information (such as EBP. In this way, when the buffer zone overflows, Canary word will be overwritten before the returned address is overwritten

In the section above, we learned to intercept the traffic for Java Applets. in this section, we will learn to intercept the traffic for JAR applications. for example, we will try to intercept the traffic from the BURP proxy tool (JAR based proxy tool) to the specified Noop tool.

Their stack addresses are different.This is accomplished by allocating a random size space between 0--n bytes on the stack at the beginning of the program. The program does not use this space, but it causes the subsequent stack position to change every time the program executes.In Linux systems, Stack randomization has become a standard behavior.

Iv. Stack CanariesFirst look at the evolution history of Stack Canaries:Stack Guard was the first to be implemented using the Canaries probe, which was released as an extension of GCC in 1997. The original version of Stack Guard uses 0x00000000 as canary Word. Although many people recommend that stack guard be included in GCC as part of GCC, it provides the protection of stacks. In practice, however, the GCC 3.x does not implement any stack protection
