Summary

c-ares security update

Details

This is c-ares, an asynchronous resolver library. It is intended for applications which need to perform DNS queries without blocking, or need to perform multiple

Security Fix(es):

In 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)
