Full description The exploitation of buffer overflow and foThe exploitation of buffer overflow and format string vulnerabilities in process stacks are a significant portion of security attacks. 'libsafe' is based on a middleware software layer that intercepts all function calls made to library functions known to be vulnerable. A substitute version of the corresponding function implements the original function in a way that ensures that any buffer overflows are contained within the current stack frame, which prevents attackers from overwriting the return address and hijacking the control flow of a running program. The true benefit of using libsafe is protection against future attacks on programs not yet known to be vulnerable. The performance overhead of libsafe is negligible, it does not require changes to the OS, it works with existing binary programs, and it does not need access to the source code of defective programs, or recompilation or off-line processing of binaries.lation or off-line processing of binaries.
