A security code reviewer has been engaged to manually review a legacy application. A number of systemic issues have been uncovered relating to buffer overflows and format string vulnerabilities. The…

C is an unmanaged language that requires explicit manual memory management, making it directly and inherently susceptible to buffer overflow and format string vulnerabilities.

C# executes on the .NET Common Language Runtime (CLR), which enforces automatic memory management, type safety, and bounds checking, preventing buffer overflows and format string attacks at the runtime level rather than relying on developer discipline.

C++ is also unmanaged and permits direct memory manipulation via raw pointers, retaining the same classes of memory safety vulnerabilities as C.

Perl is an interpreted language but does not provide the strict memory safety guarantees enforced by a managed runtime such as the CLR or JVM, so it does not qualify as a managed code platform in this context.

Java executes on the Java Virtual Machine (JVM), which performs automatic garbage collection and enforces strict type safety, eliminating the pointer arithmetic and manual memory allocation that are the root causes of buffer overflow vulnerabilities.
