Buffer Overflow in musl libc DNS Parsing

CVE-2017-15650 · MEDIUM Severity

AV:N/AC:L/AU:N/C:N/I:N/A:P

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.
