From ver 1.32.3 until 1.34.7, a use-after-free / double-free in c-ares&#39; query-completion handling. The same flaw — a query&#39;s callback being invoked while the query is still linked in the channel&#39;s internal lookup structures — is present at multiple points in the resend/finish path (timeout handling, response handling, and query dispatch). If the query, or for ares_getaddrinfo() the owning host_query, is freed as a side effect of that callback, it is then accessed and/or freed a second time. This vulnerability is fixed in ver 1.34.7.</p> <p><strong>Affected:</strong> c-ares</p> <p>c-ares is an asynchronous resolver library.
