    #include <stdio.h>
#include <stdlib.h>
int main() {
// Initialization of a pointer to a heap memory space
int *ptr = malloc(10 * sizeof(int));
// Processing of a maliciously crafted file leading to heap corruption
if (ptr == NULL) {
printf("Memory not allocated.\n");
exit(0);
}
else {
// Memory has been successfully allocated
printf("Memory successfully allocated using malloc.\n");
// Get the element of the array
for (int i = 0; i < 10; ++i) {
ptr[i] = i + 1;
}
// Access memory beyond the malloc'd area
printf("Accessing beyond allocated memory space...\n");
ptr[10] = 11;  // This line of code leads to heap corruption
}
return 0;
}

    Please note that the above is merely a conceptual representation of how heap corruption could occur. The actual exploitation of this vulnerability would require a much more sophisticated and malicious crafting of the file.

    Prevention and Mitigation

    The recommended mitigation for this vulnerability is to apply the vendor’s patch. In cases where the patch cannot be immediately applied, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. However, these should not be seen as long-term solutions, as they do not address the root cause of the vulnerability. Regular system updates and patches are vital to maintaining system security.
