CVE-2017-15650

Priority
Description
musl libc before 1.1.17 has a buffer overflow via crafted DNS replies
because dns_parse_callback in network/lookup_name.c does not restrict the
number of addresses, and thus an attacker can provide an unexpected number
by sending A records in a reply to an AAAA query.
