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.
Example 1:
Code: IMPEG2D_ERROR_CODES_T impeg2d_dec_seq_ext_data(dec_state_t *ps_dec)
{
stream_t *ps_stream;
UWORD32 u4_start_code;
IMPEG2D_ERROR_CODES_T e_error;
e_error = (IMPEG2D_ERROR_CODES_T) IVD_ERROR_NONE;
ps_stream = &ps_dec->s_bit_stream;
u4_start_code = impeg2d_bit_stream_nxt(ps_stream,START_CODE_LEN);
while( (u4_start_code == EXTENSION_START_CODE ||
u4_start_code == USER_DATA_START_CODE) &&
(IMPEG2D_ERROR_CODES_T)IVD_ERROR_NONE == e_error)
{
if(u4_start_code == USER_DATA_START_CODE)
{
impeg2d_dec_user_data(ps_dec);
}
else
{
impeg2d_bit_stream_flush(ps_stream,START_CODE_LEN);
u4_start_code = impeg2d_bit_stream_nxt(ps_stream,EXT_ID_LEN);
switch(u4_start_code)
{
case SEQ_DISPLAY_EXT_ID:
impeg2d_dec_seq_disp_ext(ps_dec);
break;
case SEQ_SCALABLE_EXT_ID:
e_error = IMPEG2D_SCALABILITIY_NOT_SUPPORTED;
break;
default:
/* In case its a reserved extension code */
impeg2d_bit_stream_flush(ps_stream,EXT_ID_LEN);
impeg2d_peek_next_start_code(ps_dec);
break;
}
}
u4_start_code = impeg2d_bit_stream_nxt(ps_stream,START_CODE_LEN);
}
return e_error;
}
CWE ID: CWE-254
Target: 1
Example 2:
Code: struct trace_entry *trace_find_next_entry(struct trace_iterator *iter,
int *ent_cpu, u64 *ent_ts)
{
return __find_next_entry(iter, ent_cpu, NULL, ent_ts);
}
CWE ID: CWE-787
Target: 0
Now analyze the following code and CWE ID. Determine whether it has a vulnerability. If it does, return '1'; if it doesn't, return '0'. Remember, I want response in '1' or '0'. Do Not respond with explanation.
Code: static void vmxnet3_fill_stats(VMXNET3State *s)
{
int i;
PCIDevice *d = PCI_DEVICE(s);
if (!s->device_active)
return;
for (i = 0; i < s->txq_num; i++) {
pci_dma_write(d,
s->txq_descr[i].tx_stats_pa,
&s->txq_descr[i].txq_stats,
sizeof(s->txq_descr[i].txq_stats));
}
for (i = 0; i < s->rxq_num; i++) {
pci_dma_write(d,
s->rxq_descr[i].rx_stats_pa,
&s->rxq_descr[i].rxq_stats,
sizeof(s->rxq_descr[i].rxq_stats));
}
}
CWE ID: CWE-200
