Summary
ntp vulnerabilities
Details
Yihan Lian discovered that NTP incorrectly handled certain large request data values. A remote attacker could possibly use this issue to cause NTP to crash, resulting in a denial of service. This issue only affected Ubuntu 16.04 LTS. (CVE-2016-2519)
Miroslav Lichvar discovered that NTP incorrectly handled certain spoofed addresses when performing rate limiting. A remote attacker could possibly use this issue to perform a denial of service. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, and Ubuntu 16.10. (CVE-2016-7426)
Matthew Van Gundy discovered that NTP incorrectly handled certain crafted broadcast mode packets. A remote attacker could possibly use this issue to perform a denial of service. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, and Ubuntu 16.10. (CVE-2016-7427, CVE-2016-7428)
Miroslav Lichvar discovered that NTP incorrectly handled certain responses. A remote attacker could possibly use this issue to perform a denial of service. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, and Ubuntu 16.10. (CVE-2016-7429)
Sharon Goldberg and Aanchal Malhotra discovered that NTP incorrectly handled origin timestamps of zero. A remote attacker could possibly use this issue to bypass the origin timestamp protection mechanism. This issue only affected Ubuntu 16.10. (CVE-2016-7431)
Brian Utterback, Sharon Goldberg and Aanchal Malhotra discovered that NTP incorrectly performed initial sync calculations. This issue only applied to Ubuntu 16.04 LTS and Ubuntu 16.10. (CVE-2016-7433)
Magnus Stubman discovered that NTP incorrectly handled certain mrulist queries. A remote attacker could possibly use this issue to cause NTP to crash, resulting in a denial of service. This issue only affected Ubuntu 16.04 LTS and Ubuntu 16.10. (CVE-2016-7434)
Matthew Van Gund discovered that NTP incorrectly handled origin timestamp checks. A remote attacker could possibly use this issue to perform a denial of service. This issue only affected Ubuntu Ubuntu 16.10, and Ubuntu 17.04. (CVE-2016-9042)
Matthew Van Gundy discovered that NTP incorrectly handled certain control mode packets. A remote attacker could use this issue to set or unset traps. This issue only applied to Ubuntu 14.04 LTS, Ubuntu 16.04 LTS and Ubuntu 16.10. (CVE-2016-9310)
Matthew Van Gundy discovered that NTP incorrectly handled the trap service. A remote attacker could possibly use this issue to cause NTP to crash, resulting in a denial of service. This issue only applied to Ubuntu 14.04 LTS, Ubuntu 16.04 LTS and Ubuntu 16.10. (CVE-2016-9311)
It was discovered that NTP incorrectly handled memory when processing long variables. A remote authenticated user could possibly use this issue to cause NTP to crash, resulting in a denial of service. (CVE-2017-6458)
It was discovered that NTP incorrectly handled memory when processing long variables. A remote authenticated user could possibly use this issue to cause NTP to crash, resulting in a denial of service. This issue only applied to Ubuntu 16.04 LTS, Ubuntu 16.10 and Ubuntu 17.04. (CVE-2017-6460)
It was discovered that the NTP legacy DPTS refclock driver incorrectly handled the /dev/datum device. A local attacker could possibly use this issue to cause a denial of service. (CVE-2017-6462)
It was discovered that NTP incorrectly handled certain invalid settings in a :config directive. A remote authenticated user could possibly use this issue to cause NTP to crash, resulting in a denial of service. (CVE-2017-6463)
It was discovered that NTP incorrectly handled certain invalid mode configuration directives. A remote authenticated user could possibly use this issue to cause NTP to crash, resulting in a denial of service. (CVE-2017-6464)
