Integer overflow in the source code tool_cb_prg.c

## Summary: Integer overflow in the source code tool_cb_prg.c ## Steps To Reproduce: Review the source code of tool_cb_prg.c In the function fly, pay attention to Line 80, 82, 84 ```C 69 static void fly(struct ProgressData *bar, bool moved) 70 { 71 char buf[256]; 72 int pos; 73 int check = bar->width - 2; 74 75 msnprintf(buf, sizeof(buf), "%*s\r", bar->width-1, " "); 76 memcpy(&buf[bar->bar], "-=O=-", 5); 77 78 pos = sinus[bar->tick%200] / (10000 / check); 79 buf[pos] = '#'; 80 pos = sinus[(bar->tick + 5)%200] / (10000 / check); 81 buf[pos] = '#'; 82 pos = sinus[(bar->tick + 10)%200] / (10000 / check); 83 buf[pos] = '#'; 84 pos = sinus[(bar->tick + 15)%200] / (10000 / check); 85 buf[pos] = '#'; ``` in Line 80, Line 82, Line 84, there are integer overflow issues. the type of 'tick' is 'unsigned int' bar->tick could be a large value, then bar->tick + 5 may revert to a small value. Here no big impact and only logic error. I think maybe a logic like this is better to avoid integer overflow. `pos = sinus[((bar->tick)%200 + 5)%200] / (10000 / check);` I am not sure if I directly create this issue on github is the correct way, so I report it here. ## Supporting Material/References: [list any additional material (e.g. screenshots, logs, etc.)] * [attachment / reference] The output of the my self-development code scan tool: [Scanning] /home/a/Data/curl/src/tool_cb_prg.c Integer Overflow found in file: /home/a/Data/curl/src/tool_cb_prg.c, Line: 80, Column: 28 pos = sinus[(bar->tick + 5)%200] / (10000 / check); Integer Overflow found in file: /home/a/Data/curl/src/tool_cb_prg.c, Line: 82, Column: 28 pos = sinus[(bar->tick + 10)%200] / (10000 / check); Integer Overflow found in file: /home/a/Data/curl/src/tool_cb_prg.c, Line: 84, Column: 28 pos = sinus[(bar->tick + 15)%200] / (10000 / check); ## Impact This integer overflow has no big impact and only may cause business logic error.
