Bug#890548: Stack buffer overflows

[Jeff Breidenbach]

This is just about strings, right? So something like this will fix the
problem
and resolve this bug? Or am I missing something?

char buf[L_BUF_SIZE];
-   fscanf(fp, "Rootname: %s\n", buf);
+   fscanf(fp, "Rootname: %L_BUF_SIZE_MINUS_ONEs%\n", buf);
