It is intended for applications which need to perform DNS queries without blocking, or need to perform multiple\r\n\r\nSecurity Fix(es):\r\n\r\nIn ares_set_sortlist, it calls config_sortlist(..., sortstr) to parse the input str and initialize a sortlist configuration. However, ares_set_sortlist has not any checks about the validity of the input str. It is very easy to create an arbitrary length stack overflow with the unchecked memcpy(ipbuf, str, q-str); and memcpy(ipbufpfx, str, q-str); statements in the config_sortlist call, which could potentially cause severe security impact in practical programs.(CVE-2022-4904)",
