The remote host is affected by the vulnerability described in GLSA-201509-01 (NTP: Multiple vulnerablities)

    Multiple vulnerabilities have been discovered in NTP. Please review the       CVE identifiers referenced below for details.
  Impact :

    A remote attacker could possibly execute arbitrary code with the       privileges of the process, or cause a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

According to the versions of the ntp packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - NTP before 4.2.8p7 and 4.3.x before 4.3.92 allows     remote attackers to cause a denial of service (prevent     subsequent authentication) by leveraging knowledge of     the controlkey or requestkey and sending a crafted     packet to ntpd, which changes the value of trustedkey,     controlkey, or requestkey. NOTE: this vulnerability     exists because of a CVE-2016-2516     regression.(CVE-2016-2517)

  - NTP before 4.2.8p6 and 4.3.x before 4.3.90, when     configured in broadcast mode, allows man-in-the-middle     attackers to conduct replay attacks by sniffing the     network.(CVE-2015-7973)

  - ntpd in ntp before 4.2.8p3 with remote configuration     enabled allows remote authenticated users with     knowledge of the configuration password and access to a     computer entrusted to perform remote configuration to     cause a denial of service (service crash) via a NULL     byte in a crafted configuration directive     packet.(CVE-2015-5146)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

New ntp packages are available for Slackware 13.0, 13.1, 13.37, 14.0, 14.1, and -current to fix a security issue.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - ntpd in ntp before 4.2.8p3 with remote configuration enabled allows remote authenticated users with     knowledge of the configuration password and access to a computer entrusted to perform remote configuration     to cause a denial of service (service crash) via a NULL byte in a crafted configuration directive packet.
    (CVE-2015-5146)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Fedora 22 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2015-14212 advisory.

    Security fix for CVE-2015-5146, CVE-2015-5194, CVE-2015-5219, CVE-2015-5195, CVE-2015-5196

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

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

The remote Fedora 21 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2015-77bfbc1bcd advisory.
