Background\n\nThe ntpd(8) daemon is an implementation of the Network Time Protocol (NTP)\nused to synchronize the time of a computer system to a reference time\nsource. \n\nII.  Problem Description\n\nCrypto-NAK packets can be used to cause ntpd(8) to accept time from an\nunauthenticated ephemeral symmetric peer by bypassing the authentication\nrequired to mobilize peer associations. [CVE-2015-7871] FreeBSD 9.3 and\n10.1 are not affected. \n\nIf ntpd(8) is fed a crafted mode 6 or mode 7 packet containing an unusual\nlong data value where a network address is expected, the decodenetnum()\nfunction will abort with an assertion failure instead of simply returning\na failure condition. [CVE-2015-7855]\n\nIf ntpd(8) is configured to allow remote configuration, and if the\n(possibly spoofed) source IP address is allowed to send remote\nconfiguration requests, and if the attacker knows the remote\nconfiguration password or if ntpd(8) was configured to disable\nauthentication, then an attacker can send a set of packets to ntpd(8) that\nmay cause it to crash, with the hypothetical possibility of a small code\ninjection. [CVE-2015-7854]\n\nA negative value for the datalen parameter will overflow a data buffer. \nNTF\u0027s ntpd(8) driver implementations always set this value to 0 and are\ntherefore not vulnerable to this weakness. If you are running a custom\nrefclock driver in ntpd(8) and that driver supplies a negative value for\ndatalen (no custom driver of even minimal competence would do this)\nthen ntpd would overflow a data buffer. It is even hypothetically\npossible in this case that instead of simply crashing ntpd the\nattacker could effect a code injection attack. [CVE-2015-7853]\n\nIf an attacker can figure out the precise moment that ntpq(8) is listening\nfor data and the port number it is listening on or if the attacker can\nprovide a malicious instance ntpd(8) that victims will connect to then an\nattacker can send a set of crafted mode 6 response packets that, if\nreceived by ntpq(8), can cause ntpq(8) to crash. [CVE-2015-7852]\n\nIf ntpd(8) is configured to allow remote configuration, and if the\n(possibly spoofed) IP address is allowed to send remote configuration\nrequests, and if the attacker knows the remote configuration password\nor if ntpd(8) was configured to disable authentication, then an attacker\ncan send a set of packets to ntpd that may cause ntpd(8) to overwrite\nfiles. [CVE-2015-7851].  The default configuration of ntpd(8) within\nFreeBSD does not allow remote configuration. \n\nIf ntpd(8) is configured to allow remote configuration, and if the\n(possibly spoofed) source IP address is allowed to send remote\nconfiguration requests, and if the attacker knows the remote\nconfiguration password or if ntpd(8) was configured to disable\nauthentication, then an attacker can send a set of packets to ntpd\nthat will cause it to crash and/or create a potentially huge log\nfile.  Specifically, the attacker could enable extended logging,\npoint the key file at the log file, and cause what amounts to an\ninfinite loop. [CVE-2015-7850].  The default configuration of ntpd(8)\nwithin FreeBSD does not allow remote configuration. \n\nIf ntpd(8) is configured to allow remote configuration, and if the\n(possibly spoofed) source IP address is allowed to send remote\nconfiguration requests, and if the attacker knows the remote\nconfiguration password or if ntpd was configured to disable\nauthentication, then an attacker can send a set of packets to\nntpd that may cause a crash or theoretically perform a code\ninjection attack. [CVE-2015-7849].  The default configuration of ntpd(8)\nwithin FreeBSD does not allow remote configuration. \n\nIf ntpd(8) is configured to enable mode 7 packets, and if the use\nof mode 7 packets is not properly protected thru the use of the\navailable mode 7 authentication and restriction mechanisms, and\nif the (possibly spoofed) source IP address is allowed to send\nmode 7 queries, then an attacker can send a crafted packet to\nntpd that will cause it to crash. [CVE-2015-7848].  The default\nconfiguration of ntpd(8) within FreeBSD does not allow mode 7\npackets. \n\nIf ntpd(8) is configured to use autokey, then an attacker can send\npackets to ntpd that will, after several days of ongoing attack,\ncause it to run out of memory. [CVE-2015-7701].  The default\nconfiguration of ntpd(8) within FreeBSD does not use autokey. \n\nIf ntpd(8) is configured to allow for remote configuration, and if\nthe (possibly spoofed) source IP address is allowed to send\nremote configuration requests, and if the attacker knows the\nremote configuration password, it\u0027s possible for an attacker\nto use the \"pidfile\" or \"driftfile\" directives to potentially\noverwrite other files. [CVE-2015-5196].  The default configuration\nof ntpd(8) within FreeBSD does not allow remote configuration\n\nAn ntpd(8) client that honors Kiss-of-Death responses will honor\nKoD messages that have been forged by an attacker, causing it\nto delay or stop querying its servers for time updates. Also,\nan attacker can forge packets that claim to be from the target\nand send them to servers often enough that a server that\nimplements KoD rate limiting will send the target machine a\nKoD response to attempt to reduce the rate of incoming packets,\nor it may also trigger a firewall block at the server for\npackets from the target machine. For either of these attacks\nto succeed, the attacker must know what servers the target\nis communicating with. An attacker can be anywhere on the\nInternet and can frequently learn the identity of the target\u0027s\ntime source by sending the target a time query. [CVE-2015-7704]\n\nThe fix for CVE-2014-9750 was incomplete in that there were\ncertain code paths where a packet with particular autokey\noperations that contained malicious data was not always being\ncompletely validated. Receipt of these packets can cause ntpd\nto crash. [CVE-2015-7702].  The default configuration of ntpd(8)\nwithin FreeBSD does not use autokey. \n\nIII. Impact\n\nAn attacker which can send NTP packets to ntpd(8), which uses cryptographic\nauthentication of NTP data, may be able to inject malicious time data\ncausing the system clock to be set incorrectly. [CVE-2015-7871]\n\nAn attacker which can send NTP packets to ntpd(8), can block the\ncommunication of the daemon with time servers, causing the system\nclock not being synchronized. [CVE-2015-7704]\n\nAn attacker which can send NTP packets to ntpd(8), can remotely crash\nthe daemon, sending malicious data packet. [CVE-2015-7855] [CVE-2015-7854]\n[CVE-2015-7853] [CVE-2015-7852] [CVE-2015-7849] [CVE-2015-7848]\n\nAn attacker which can send NTP packets to ntpd(8), can remotely\ntrigger the daemon to overwrite its configuration files. [CVE-2015-7851]\n[CVE-2015-5196]\n\nIV.  Workaround\n\nNo workaround is available, but systems not running ntpd(8) are not\naffected.  Network administrators are advised to implement BCP-38,\nwhich helps to reduce risk associated with the attacks. \n\nV.   Solution\n\nPerform one of the following:\n\n1) Upgrade your vulnerable system to a supported FreeBSD stable or\nrelease / security branch (releng) dated after the correction date. \n\nThe ntpd service has to be restarted after the update.  A reboot is\nrecommended but not required. \n\n2) To update your vulnerable system via a binary patch:\n\nSystems running a RELEASE version of FreeBSD on the i386 or amd64\nplatforms can be updated via the freebsd-update(8) utility:\n\n# freebsd-update fetch\n# freebsd-update install\n\nThe ntpd service has to be restarted after the update.
