    CVE-2017-15650

    Published: 19 Oct 2017Last Modified: 2 Sept 2026

    Summary:

    Details: 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.
