Here are some example code snippets. Analyze the following code and CWE ID and the target value where 1 indicates the code has vulnerability and 0 indicates non-vulnerable code.

/* Get some constants derived from the input and output file formats: */
PNG_CONST png_store* PNG_CONST ps = dp->this.ps;

PNG_CONST png_byte out_ct = png_get_color_type(pp, pi);
PNG_CONST png_byte out_bd = png_get_bit_depth(pp, pi);
/* There are three sources of error, firstly the quantization in the
* file encoding, determined by sbit and/or the file depth, secondly
* the output (screen) gamma and thirdly the output file encoding.
*
* Since this API receives the screen and file gamma in double
* precision it is possible to calculate an exact answer given an input
* pixel value. Therefore we assume that the *input* value is exact -
* sample/maxsample - calculate the corresponding gamma corrected
* output to the limits of double precision arithmetic and compare with
* what libpng returns.
*
* Since the library must quantize the output to 8 or 16 bits there is
* a fundamental limit on the accuracy of the output of +/-.5 - this
* quantization limit is included in addition to the other limits
* specified by the paramaters to the API. (Effectively, add .5
* everywhere.)
*
* The behavior of the 'sbit' paramter is defined by section 12.5
* (sample depth scaling) of the PNG spec. That section forces the
* decoder to assume that the PNG values have been scaled if sBIT is
* present:
*
* png-sample = floor( input-sample * (max-out/max-in) + .5);
*
* This means that only a subset of the possible PNG values should
* appear in the input. However, the spec allows the encoder to use a
* variety of approximations to the above and doesn't require any
* restriction of the values produced.
*
* Nevertheless the spec requires that the upper 'sBIT' bits of the
* value stored in a PNG file be the original sample bits.
* Consequently the code below simply scales the top sbit bits by
* (1<<sbit)-1 to obtain an original sample value.
*
* Because there is limited precision in the input it is arguable that
* an acceptable result is any valid result from input-.5 to input+.5.
* The basic tests below do not do this, however if 'use_input_precision'
* is set a subsequent test is performed above.
