FINAL RESULTS:
data/easychem-0.6/bonds.c:1527:7: [4] (format) fprintf:
If format strings can be influenced by an attacker, they can be exploited
(CWE-134). Use a constant for the format specification.
fprintf (file, "%s %" LLFORMAT " %" LLFORMAT " %" LLFORMAT " %" LLFORMAT
data/easychem-0.6/bonds.c:1649:7: [4] (buffer) fscanf:
The scanf() family's %s operation, without a limit specification, permits
buffer overflows (CWE-120, CWE-20). Specify a limit to %s, or use a
different input function. If the scanf format is influenceable by an
attacker, it's exploitable.
