CVE-2017-15650: Musl-Libc Musl

High severity, CVSS 7.5. EPSS: 2% chance of exploitation in the next 30 days.

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.

Affected products

• Musl-Libc Musl: up to and including 1.1.6
