Multiple stack-based buffer overflows in the __dn_expand function in network/dn_expand.c in musl libc 1.1x before 1.1.2 and 0.9.13 through 1.0.3 allow remote attackers to (1) have unspecified impact via an invalid name length in a DNS response or (2) cause a denial of service (crash) via an invalid name length in a DNS response, related to an infinite loop with no output.

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.
