CVE-2017-15650

HIGH

musl libc < 1.1.17 - Buffer Overflow via Crafted DNS Reply

Title source: llm
STIX 2.1

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.
