Summary: Stack Overflow protection |
The libsafe library is designed to overwrite dangerous library C function like strcpy / snprintf and perform bound checking on the destination buffer address in order to detect an eventual Stack Overflow attempt. The libsafe library protects a process against the exploitation of buffer overflow vulnerabilities in process stacks. Libsafe works with any existing pre-compiled executable and can be used transparently, even on a system-wide basis. The method intercepts all calls to library functions that are known to be vulnerable. A substitute version of the corresponding function implements the original functionality, but in a manner that ensures that any buffer overflows are contained within the current stack frame. Libsafe has been shown to detect several known attacks and can potentially prevent yet unknown attacks. Experiments indicate that the performance overhead of libsafe is negligible.
