FORTIFY vsprintf prevented 571-byte write into 256-byte buffer

This error message indicates that there is an attempted buffer overflow in the vsprintf function. Specifically, the program is trying to write 571 bytes into a buffer that can only hold 256 bytes, which could lead to memory corruption and potentially cause a security vulnerability.

The Fortify tool has detected this issue and prevented it from happening, which is a good thing as it helps to avoid potential security risks. However, the root cause of the error needs to be identified and fixed to ensure that the program is functioning correctly.

To fix this issue, the buffer size needs to be increased to accommodate the amount of data being written to it. Alternatively, the vsprintf function can be replaced with a safer alternative, such as snprintf, which allows the programmer to specify the maximum number of characters that can be written to the buffer
