In the case of stack buffer overflows, the issue applies to the stack, which is the memory space used by the operating system primarily to store local variables and function return addresses. The data on the stack is stored and retrieved in an organized fashion (last-in-first-out), the s...
A buffer overflow occurs when a program or process attempts to write more data to a fixed-length block of memory, or buffer, than the buffer is allocated to hold. Buffers contain a defined amount of data; any extra data will overwrite data values in memory addresses adjacent to the destinat...
What is Buffer Overflow Attack in cyber security Buffer Overflow Attacksoccur as a result of excess data being input into a system memory buffer. Moreover, when the memory buffer’s capacity has been reached, the music will stop playing. To avoid overwriting other data in your computer’s mem...
High-level languages don’t have this issue because they abstract the memory allocation away from the user and manage it automatically. Conclusion A buffer overflow is a class of security vulnerability when the memory area allocated for a variable is exceeded by the data placed within it. Instead...

As you may have heard, Whatsapp discovered a security issue in their client which wasactively exploited in the wild. The exploit did not require the target to pick up the call which is really scary. Since there are not many facts to go on, lets do some tea reading… ...
and serverless platforms. Cloud native security is a complex challenge, because cloud native applications have a large number of moving parts and components tend to be ephemeral—frequently torn down and replaced by others. This makes it difficult to gain visibility over a cloud native environment ...
