For some rare inputs with a large number of distant matches (crafted payloads), the buffer into which the compressed or deflated data is written can overwrite the distance symbol table which it overlays. This issue results in corrupted output due to invalid distances, which leads to out-of-bound access, corrupting the memory and potentially crashing the application.(CVE-2018-25032)");
