Detail
A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS Summary: Several security issues were fixed in NTP. Software Description: - ntp: Network Time Protocol daemon and utility programs Details: Aanchal Malhotra discovered that NTP incorrectly handled authenticated broadcast mode. A remote attacker could use this issue to perform a replay attack. (CVE-2015-7973) Matt Street discovered that NTP incorrectly verified peer associations of symmetric keys. A remote attacker could use this issue to perform an impersonation attack. (CVE-2015-7974) Jonathan Gardner discovered that the NTP ntpq utility incorrectly handled memory. An attacker could possibly use this issue to cause ntpq to crash, resulting in a denial of service. This issue only affected Ubuntu 16.04 LTS. (CVE-2015-7975) Jonathan Gardner discovered that the NTP ntpq utility incorrectly handled dangerous characters in filenames. An attacker could possibly use this issue to overwrite arbitrary files. (CVE-2015-7976) Stephen Gray discovered that NTP incorrectly handled large restrict lists. An attacker could use this issue to cause NTP to crash, resulting in a denial of service. (CVE-2015-7977, CVE-2015-7978) Aanchal Malhotra discovered that NTP incorrectly handled authenticated broadcast mode. A remote attacker could use this issue to cause NTP to crash, resulting in a denial of service. (CVE-2015-7979) Jonathan Gardner discovered that NTP incorrectly handled origin timestamp checks. A remote attacker could use this issue to spoof peer servers. (CVE-2015-8138) Jonathan Gardner discovered that the NTP ntpq utility did not properly handle certain incorrect values. An attacker could possibly use this issue to cause ntpq to hang, resulting in a denial of service. (CVE-2015-8158) It was discovered that the NTP cronjob incorrectly cleaned up the statistics directory. A local attacker could possibly use this to escalate privileges. (CVE-2016-0727) Stephen Gray and Matthew Van Gundy discovered that NTP incorrectly validated crypto-NAKs. A remote attacker could possibly use this issue to prevent clients from synchronizing. (CVE-2016-1547) Miroslav Lichvar and Jonathan Gardner discovered that NTP incorrectly handled switching to interleaved symmetric mode. A remote attacker could possibly use this issue to prevent clients from synchronizing. (CVE-2016-1548) Matthew Van Gundy, Stephen Gray and Loganaden Velvindron discovered that NTP incorrectly handled message authentication. A remote attacker could possibly use this issue to recover the message digest key. (CVE-2016-1550) Yihan Lian discovered that NTP incorrectly handled duplicate IPs on unconfig directives. An authenticated remote attacker could possibly use this issue to cause NTP to crash, resulting in a denial of service. (CVE-2016-2516) Yihan Lian discovered that NTP incorrectly handled certail peer associations. A remote attacker could possibly use this issue to cause NTP to crash, resulting in a denial of service. (CVE-2016-2518) Jakub Prokes discovered that NTP incorrectly handled certain spoofed packets. A remote attacker could possibly use this issue to cause a denial of service. (CVE-2016-4954) Miroslav Lichvar discovered that NTP incorrectly handled certain packets when autokey is enabled. A remote attacker could possibly use this issue to cause a denial of service. (CVE-2016-4955) Miroslav Lichvar discovered that NTP incorrectly handled certain spoofed broadcast packets. A remote attacker could possibly use this issue to cause a denial of service. (CVE-2016-4956) In the default installation, attackers would be isolated by the NTP AppArmor profile. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 LTS: Ubuntu 14.04 LTS: Ubuntu 12.04 LTS: In general, a standard system update will make all the necessary changes.
