Detail
| A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 12.04 ESM Summary: Several security issues were fixed in NTP. Software Description: - ntp: Network Time Protocol daemon and utility programs Details: USN-3707-1 and USN-3349-1 fixed several vulnerabilities in NTP. This update provides the corresponding update for Ubuntu 12.04 ESM. Original advisory details: ﾃつ Miroslav Lichvar discovered that NTP incorrectly handled certain ﾃつ spoofed addresses when performing rate limiting. A remote attacker ﾃつ could possibly use this issue to perform a denial of service. ﾃつ (CVE-2016-7426) ﾃつ Matthew Van Gundy discovered that NTP incorrectly handled certain ﾃつ crafted broadcast mode packets. A remote attacker could possibly use ﾃつ this issue to perform a denial of service.ﾃつ ﾃつ (CVE-2016-7427, CVE-2016-7428) ﾃつ Matthew Van Gundy discovered that NTP incorrectly handled certain ﾃつ control mode packets. A remote attacker could use this issue to set or ﾃつ unset traps. (CVE-2016-9310) ﾃつ Matthew Van Gundy discovered that NTP incorrectly handled the trap ﾃつ service. A remote attacker could possibly use this issue to cause NTP ﾃつ to crash, resulting in a denial of service. (CVE-2016-9311) ﾃつ It was discovered that the NTP legacy DPTS refclock driver incorrectly ﾃつ handled the /dev/datum device. A local attacker could possibly use ﾃつ this issue to cause a denial of service. (CVE-2017-6462) ﾃつ It was discovered that NTP incorrectly handled certain invalid ﾃつ settings in a :config directive. A remote authenticated user could ﾃつ possibly use this issue to cause NTP to crash, resulting in a denial ﾃつ of service.
