Stack-based buffer overflow in the inet_pton function in network/inet_pton.c in musl libc 0.9.15 through 1.0.4, and 1.1.0 through 1.1.7 allows attackers to have unspecified impact via unknown vectors.

The remote Ubuntu 16.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4768-1 advisory.

    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 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 16.04 ESM. (CVE-2017-15650)

    It was discovered that musl did not properly handle the parsing of ipv6 addresses. An attacker could use     this vulnerability to cause a denial of service (crash) or possibly execute arbitrary code. This issue     only affected Ubuntu 14.04 ESM. (CVE-2015-1817)

    It was discovered that TRE library, used by musl, did not properly handle certain inputs. An attacker     could use this vulnerability to cause a denial of service (crash). (CVE-2016-8859)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Stack-based buffer overflow in the inet_pton function in network/inet_pton.c in musl libc 0.9.15 through
    1.0.4, and 1.1.0 through 1.1.7 allows attackers to have unspecified impact via unknown vectors.
    (CVE-2015-1817)
