Security vulnerabilities and automated fixes for string handling issues

A high-severity buffer overflow vulnerability was discovered in `generic/eth-impl.c`, where unsafe `strncpy()` and `sprintf()` calls could write beyond buffer boundaries when handling network interface names and device filenames. The fix replaced these dangerous functions with bounded `snprintf()` calls that guarantee null-termination and prevent memory corruption.
A high-severity buffer overflow vulnerability was discovered in the Aroma UI framework's textbox widget where `strncpy()` was used to copy user-provided text without guaranteed null-termination safety. The fix replaces the dangerous `strncpy()` pattern with `snprintf()`, which automatically handles buffer boundaries and null-termination in a single, safer operation.
