What is the purpose of the "safe buffer" shim library mentioned in the didactic material?
The "safe buffer" shim library mentioned in the didactic material serves a important purpose in the realm of web application security, specifically in the context of server security for local HTTP servers. This library is designed to address the vulnerabilities associated with buffer overflows, a common and potentially devastating security issue in software applications. A
What potential security vulnerability arises when a number is passed instead of a string to the buffer constructor?
When a number is passed instead of a string to the buffer constructor, a potential security vulnerability arises in the context of web application security. This vulnerability can be exploited by attackers to perform a buffer overflow attack, which can lead to the execution of arbitrary code or the manipulation of program flow. Buffer overflow
What potential security risks are associated with passing a number as the input string to the buffer constructor in Node.js?
When passing a number as the input string to the buffer constructor in Node.js, there are several potential security risks that need to be considered. These risks primarily stem from the possibility of buffer overflow and the potential for an attacker to exploit this vulnerability to execute arbitrary code or gain unauthorized access to a

How can an attacker exploit a buffer overflow vulnerability to gain unauthorized access or execute malicious code?
Buffer overflow vulnerabilities are a common type of security flaw that can be exploited by attackers to gain unauthorized access or execute malicious code on a computer system. A buffer overflow occurs when a program attempts to write data beyond the boundaries of a fixed-size buffer in memory, resulting in the overwriting of adjacent memory
