Module Name:    src

        src/libexec/telnetd: state.c

Log Message:
Fix off by one in telrcv()

In case of "\r" in the data buffer, the code was unconditionally looking ahead
to next character, even if "\r" was last character in the buffer. That
condition leads to read outside of the data (one byte after the array)

Thanks christos@ for the review
