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.

CVE-2018-1000001 [CRITICAL] musl vulnerabilities
Title: musl vulnerabilities
Summary: Several security issues were fixed in musl.
It was discovered that musl did not properly handle kernel syscalls. An
attacker could use this vulnerability to cause a denial of service (crash)
or possibly execute arbitrary code. (CVE-2018-1000001)
It was discovered that musl did not properly handle the parsing of DNS
response codes. A remote attacker could use this vulnerability to cause
resource consumption (infinite loop), denial of service, or possibly
execute arbitrary code. This issue only affected Ubuntu 14.04 ESM.
(CVE-2014-3484)
It was discovered that musl did not properly handle the parsing of DNS
