Misuse Details

Details about the known misuse from the MUBench dataset.

Description:	On line 403 `_code.charAt()` is invoked without ensuring that the respective string actually has sufficiently many characters. From the constant initialization on line 401 we take that `k` will assume the values from [0, 4], while `_code` might be any string.
Fix Description:
Violation Types:	missing/condition/value_or_state
In File:	com/itextpdf/text/pdf/BarcodeEAN.java
In Method:	getBarsSupplemental5(String)
Code with Misuse:	class BarcodeEAN { /** Creates the bars for the barcode supplemental 5. * @param _code the text with 5 digits * @return the barcode / public static byte[] getBarsSupplemental5(String _code) { int code[] = new int[5]; for (int k = 0; k < code.length; ++k) code[k] = _code.charAt(k) - '0'; byte bars[] = new byte[TOTALBARS_SUPP5]; int pb = 0; int parity = (((code[0] + code[2] + code[4]) 3) + ((code[1] + code[3]) * 9)) % 10; bars[pb++] = 1; bars[pb++] = 1; bars[pb++] = 2; byte sequence[] = PARITY5[parity]; for (int k = 0; k < sequence.length; ++k) { if (k != 0) { bars[pb++] = 1; bars[pb++] = 1; } int c = code[k]; byte stripes[] = BARS[c]; if (sequence[k] == ODD) { bars[pb++] = stripes[0]; bars[pb++] = stripes[1]; bars[pb++] = stripes[2]; bars[pb++] = stripes[3]; } else { bars[pb++] = stripes[3]; bars[pb++] = stripes[2]; bars[pb++] = stripes[1]; bars[pb++] = stripes[0]; } } return bars; } }
