CVE-2022-25514: heap-buffer-overflow in function ttUSHORT() at stb_truetype.h:1286 · Issue #1286 · nothings/stb

Describe
A heap-buffer-overflow was discovered in stb_truetype. The issue is being triggered in function ttUSHORT() at stb_truetype.h:1286
To Reproduce
test program

#include <stdio.h>  
#include <stdlib.h>
#define STB_IMAGE_WRITE_IMPLEMENTATION
#include "stb_image_write.h"
#define STB_TRUETYPE_IMPLEMENTATION
#include "stb_truetype.h"
int main(int argc, const char *argv[])
{
    long int size = 0;
    unsigned char *fontBuffer = NULL;
    FILE *fontFile = fopen(argv[1], "rb");
    if (fontFile == NULL)
    {
        printf("Can not open font file!\n");
        return 0;
    }
    fseek(fontFile, 0, SEEK_END);
    size = ftell(fontFile);   
    fseek(fontFile, 0, SEEK_SET); 
    fontBuffer = calloc(size, sizeof(unsigned char));
    fread(fontBuffer, size, 1, fontFile);
    fclose(fontFile);
    stbtt_fontinfo info;
    if (!stbtt_InitFont(&info, fontBuffer, 0))
    {
        printf("stb init font failed\n");
    }
    int bitmap_w = 512; 
    int bitmap_h = 128;
    free(fontBuffer);
    return 0;
}
