ID CVE-2015-7974
Summary NTP 4.x before 4.2.8p6 and 4.3.x before 4.3.90 do not verify peer associations of symmetric keys when authenticating packets, which might allow remote attackers to conduct impersonation attacks via an arbitrary trusted key, aka a "skeleton key."

    description NTPv3 and NTPv4 are vulnerable to : http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-7974 NTP could allow a remote authenticated attacker to conduct spoofing attacks, caused by a missing key check. An attacker could exploit this vulnerability to impersonate a peer. NTP could allow a local attacker to bypass security restrictions, caused by the failure to use a constant-time memory comparison function when validating the authentication digest on incoming packets. By sending a specially crafted packet with an authentication payload, an attacker could exploit this vulnerability to conduct a timing attack to compute the value of the valid authentication digest. While the majority OSes implement martian packet filtering in their network stack, at least regarding 127.0.0.0/8, a rare few will allow packets claiming to be from 127.0.0.0/8 that arrive over physical network. On these OSes, if ntpd is configured to use a reference clock an attacker can inject packets over the network that look like they are coming from that reference clock. If ntpd was expressly configured to allow for remote configuration, a malicious user who knows the controlkey for ntpq or the requestkey for ntpdc (if mode7 is expressly enabled) can create a session with ntpd and then send a crafted packet to ntpd that will change the value of the trustedkey, controlkey, or requestkey to a value that will prevent any subsequent authentication with ntpd until ntpd is restarted. NTP is vulnerable to a denial of service, caused by an error when using a specially crafted packet to create a peer association with hmode > 7. An attacker could exploit this vulnerability to cause the MATCH_ASSOC() function to trigger an out-of-bounds read. NTP is vulnerable to a denial of service, caused by the failure to always check the ctl_getitem() function return value. By sending an overly large value, an attacker could exploit this vulnerability to cause a denial of service. NTP is vulnerable to a denial of service, caused by the demobilization of a preemptable client association. By sending specially crafted crypto NAK packets, an attacker could exploit this vulnerability to cause a denial of service. NTP is vulnerable to a denial of service, caused by the improper handling of packets. By sending specially crafted CRYPTO_NAK packets, an attacker could exploit this vulnerability to cause ntpd to crash. NTP is vulnerable to a denial of service, caused by the improper handling of packets. By sending specially crafted CRYPTO_NAK packets to an ephemeral peer target prior to a response being sent, a remote attacker could exploit this vulnerability to demobilize the ephemeral association. NTP is vulnerable to a denial of service, caused by the improper handling of packets. By sending spoofed server packets with correct origin timestamps, a remote attacker could exploit this vulnerability to cause a false leap indication to be set. NTP is vulnerable to a denial of service, caused by the improper handling of packets. By sending spoofed CRYPTO_NAK or a bad MAC packets with correct origin timestamps, a remote attacker could exploit this vulnerability to cause the autokey association to reset.

    description The version of NTP installed on the remote AIX host is affected by the following vulnerabilities : - A time serving flaw exists in the trusted key system due to improper key checks. An authenticated, remote attacker can exploit this to perform impersonation attacks between authenticated peers. (CVE-2015-7974) - An information disclosure vulnerability exists in the message authentication functionality in libntp that is triggered during the handling of a series of specially crafted messages. An adjacent attacker can exploit this to partially recover the message digest key. (CVE-2016-1550) - A flaw exists due to improper filtering of IPv4 'bogon' packets received from a network. An unauthenticated, remote attacker can exploit this to spoof packets to appear to come from a specific reference clock. (CVE-2016-1551) - A denial of service vulnerability exists that allows an authenticated, remote attacker to manipulate the value of the trustedkey, controlkey, or requestkey via a crafted packet, preventing authentication with ntpd until the daemon has been restarted. (CVE-2016-2517) - An out-of-bounds read error exists in the MATCH_ASSOC() function that occurs during the creation of peer associations with hmode greater than 7. An authenticated, remote attacker can exploit this, via a specially crafted packet, to cause a denial of service. (CVE-2016-2518) - An overflow condition exists in the ctl_getitem() function in ntpd due to improper validation of user-supplied input when reporting return values. An authenticated, remote attacker can exploit this to cause ntpd to abort. (CVE-2016-2519)

    description Security Fix(es) : - It was found that the fix for CVE-2014-9750 was incomplete: three issues were found in the value length checks in NTP's ntp_crypto.c, where a packet with particular autokey operations that contained malicious data was not always being completely validated. A remote attacker could use a specially crafted NTP packet to crash ntpd. (CVE-2015-7691, CVE-2015-7692, CVE-2015-7702) - A memory leak flaw was found in ntpd's CRYPTO_ASSOC. If ntpd was configured to use autokey authentication, an attacker could send packets to ntpd that would, after several days of ongoing attack, cause it to run out of memory. (CVE-2015-7701) - An off-by-one flaw, leading to a buffer overflow, was found in cookedprint functionality of ntpq. A specially crafted NTP packet could potentially cause ntpq to crash. (CVE-2015-7852) - A NULL pointer dereference flaw was found in the way ntpd processed 'ntpdc reslist' commands that queried restriction lists with a large amount of entries. A remote attacker could potentially use this flaw to crash ntpd. (CVE-2015-7977) - A stack-based buffer overflow flaw was found in the way ntpd processed 'ntpdc reslist' commands that queried restriction lists with a large amount of entries. A remote attacker could use this flaw to crash ntpd. (CVE-2015-7978) - It was found that when NTP was configured in broadcast mode, a remote attacker could broadcast packets with bad authentication to all clients. The clients, upon receiving the malformed packets, would break the association with the broadcast server, causing them to become out of sync over a longer period of time. (CVE-2015-7979) - It was found that ntpd could crash due to an uninitialized variable when processing malformed logconfig configuration commands. (CVE-2015-5194) - It was found that ntpd would exit with a segmentation fault when a statistics type that was not enabled during compilation (e.g. timingstats) was referenced by the statistics or filegen configuration command. (CVE-2015-5195) - It was found that NTP's :config command could be used to set the pidfile and driftfile paths without any restrictions. A remote attacker could use this flaw to overwrite a file on the file system with a file containing the pid of the ntpd process (immediately) or the current estimated drift of the system clock (in hourly intervals). (CVE-2015-5196, CVE-2015-7703) - It was discovered that the sntp utility could become unresponsive due to being caught in an infinite loop when processing a crafted NTP packet. (CVE-2015-5219) - A flaw was found in the way NTP verified trusted keys during symmetric key authentication. An authenticated client (A) could use this flaw to modify a packet sent between a server (B) and a client (C) using a key that is different from the one known to the client (A). (CVE-2015-7974) - A flaw was found in the way the ntpq client processed certain incoming packets in a loop in the getresponse() function. A remote attacker could potentially use this flaw to crash an ntpq client instance. (CVE-2015-8158) The CVE-2015-5219 and CVE-2015-7703 issues were discovered by Miroslav Lichvr (Red Hat).

    description The version of NTP installed on the remote AIX host is affected by the following vulnerabilities : - A time serving flaw exists in the trusted key system due to improper key checks. An authenticated, remote attacker can exploit this to perform impersonation attacks between authenticated peers. (CVE-2015-7974) - A denial of service vulnerability exists due to improper handling of a crafted Crypto NAK Packet with a source address spoofed to match that of an existing associated peer. An unauthenticated, remote attacker can exploit this to demobilize a client association. (CVE-2016-1547) - An information disclosure vulnerability exists in the message authentication functionality in libntp that is triggered during the handling of a series of specially crafted messages. An adjacent attacker can exploit this to partially recover the message digest key. (CVE-2016-1550) - A flaw exists due to improper filtering of IPv4 'bogon' packets received from a network. An unauthenticated, remote attacker can exploit this to spoof packets to appear to come from a specific reference clock. (CVE-2016-1551) - A denial of service vulnerability exists that allows an authenticated, remote attacker to manipulate the value of the trustedkey, controlkey, or requestkey via a crafted packet, preventing authentication with ntpd until the daemon has been restarted. (CVE-2016-2517) - An out-of-bounds read error exists in the MATCH_ASSOC() function that occurs during the creation of peer associations with hmode greater than 7. An authenticated, remote attacker can exploit this, via a specially crafted packet, to cause a denial of service. (CVE-2016-2518) - An overflow condition exists in the ctl_getitem() function in ntpd due to improper validation of user-supplied input when reporting return values. An authenticated, remote attacker can exploit this to cause ntpd to abort. (CVE-2016-2519) - A denial of service vulnerability exists when handling authentication due to improper packet timestamp checks. An unauthenticated, remote attacker can exploit this, via a specially crafted and spoofed packet, to demobilize the ephemeral associations.

    description NTPv3 and NTPv4 are vulnerable to : http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-7974 NTP could allow a remote authenticated attacker to conduct spoofing attacks, caused by a missing key check. An attacker could exploit this vulnerability to impersonate a peer. NTP could allow a local attacker to bypass security restrictions, caused by the failure to use a constant-time memory comparison function when validating the authentication digest on incoming packets. By sending a specially crafted packet with an authentication payload, an attacker could exploit this vulnerability to conduct a timing attack to compute the value of the valid authentication digest. While the majority OSes implement martian packet filtering in their network stack, at least regarding 127.0.0.0/8, a rare few will allow packets claiming to be from 127.0.0.0/8 that arrive over physical network. On these OSes, if ntpd is configured to use a reference clock an attacker can inject packets over the network that look like they are coming from that reference clock. If ntpd was expressly configured to allow for remote configuration, a malicious user who knows the controlkey for ntpq or the requestkey for ntpdc (if mode7 is expressly enabled) can create a session with ntpd and then send a crafted packet to ntpd that will change the value of the trustedkey, controlkey, or requestkey to a value that will prevent any subsequent authentication with ntpd until ntpd is restarted. NTP is vulnerable to a denial of service, caused by an error when using a specially crafted packet to create a peer association with hmode > 7. An attacker could exploit this vulnerability to cause the MATCH_ASSOC() function to trigger an out-of-bounds read. NTP is vulnerable to a denial of service, caused by the failure to always check the ctl_getitem() function return value. By sending an overly large value, an attacker could exploit this vulnerability to cause a denial of service. NTP is vulnerable to a denial of service, caused by the demobilization of a preemptable client association. By sending specially crafted crypto NAK packets, an attacker could exploit this vulnerability to cause a denial of service. NTP is vulnerable to a denial of service, caused by the improper handling of packets. By sending specially crafted CRYPTO_NAK packets, an attacker could exploit this vulnerability to cause ntpd to crash. NTP is vulnerable to a denial of service, caused by the improper handling of packets. By sending specially crafted CRYPTO_NAK packets to an ephemeral peer target prior to a response being sent, a remote attacker could exploit this vulnerability to demobilize the ephemeral association. NTP is vulnerable to a denial of service, caused by the improper handling of packets. By sending spoofed server packets with correct origin timestamps, a remote attacker could exploit this vulnerability to cause a false leap indication to be set. NTP is vulnerable to a denial of service, caused by the improper handling of packets. By sending spoofed CRYPTO_NAK or a bad MAC packets with correct origin timestamps, a remote attacker could exploit this vulnerability to cause the autokey association to reset.

    description The version of the remote NTP server is 3.x or 4.x prior to 4.2.8p7. It is, therefore, affected by the following vulnerabilities : - A denial of service vulnerability exists due to improper validation of the origin timestamp field when handling a Kiss-of-Death (KoD) packet. An unauthenticated, remote attacker can exploit this to cause a client to stop querying its servers, preventing the client from updating its clock. (CVE-2015-7704) - A flaw exists in the receive() function in ntp_proto.c that allows packets with an origin timestamp of zero to bypass security checks. An unauthenticated, remote attacker can exploit this to spoof arbitrary content. (CVE-2015-8138) - A denial of service vulnerability exists due to improper handling of a crafted Crypto NAK Packet with a source address spoofed to match that of an existing associated peer. An unauthenticated, remote attacker can exploit this to demobilize a client association. (CVE-2016-1547) - A denial of service vulnerability exists due to improper handling of packets spoofed to appear to be from a valid ntpd server. An unauthenticated, remote attacker can exploit this to cause NTP to switch from basic client/server mode to interleaved symmetric mode, causing the client to reject future legitimate responses. (CVE-2016-1548) - A race condition exists that is triggered during the handling of a saturation of ephemeral associations. An authenticated, remote attacker can exploit this to defeat NTP's clock selection algorithm and modify a user's clock. (CVE-2016-1549) - An information disclosure vulnerability exists in the message authentication functionality in libntp that is triggered during the handling of a series of specially crafted messages. An adjacent attacker can exploit this to partially recover the message digest key. (CVE-2016-1550) - A flaw exists due to improper filtering of IPv4 'bogon' packets received from a network. An unauthenticated, remote attacker can exploit this to spoof packets to appear to come from a specific reference clock. (CVE-2016-1551) - A denial of service vulnerability exists that allows an authenticated, remote attacker that has knowledge of the controlkey for ntpq or the requestkey for ntpdc to create a session with the same IP twice on an unconfigured directive line, causing ntpd to abort. (CVE-2016-2516) - A denial of service vulnerability exists that allows an authenticated, remote attacker to manipulate the value of the trustedkey, controlkey, or requestkey via a crafted packet, preventing authentication with ntpd until the daemon has been restarted. (CVE-2016-2517) - An out-of-bounds read error exists in the MATCH_ASSOC() function that occurs during the creation of peer associations with hmode greater than 7.

    description From Red Hat Security Advisory 2016:2583 : An update for ntp is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The Network Time Protocol (NTP) is used to synchronize a computer's time with another referenced time source. These packages include the ntpd service which continuously adjusts system time and utilities used to query and configure the ntpd service. Security Fix(es) : * It was found that the fix for CVE-2014-9750 was incomplete: three issues were found in the value length checks in NTP's ntp_crypto.c, where a packet with particular autokey operations that contained malicious data was not always being completely validated. A remote attacker could use a specially crafted NTP packet to crash ntpd. (CVE-2015-7691, CVE-2015-7692, CVE-2015-7702) * A memory leak flaw was found in ntpd's CRYPTO_ASSOC. If ntpd was configured to use autokey authentication, an attacker could send packets to ntpd that would, after several days of ongoing attack, cause it to run out of memory. (CVE-2015-7701) * An off-by-one flaw, leading to a buffer overflow, was found in cookedprint functionality of ntpq. A specially crafted NTP packet could potentially cause ntpq to crash. (CVE-2015-7852) * A NULL pointer dereference flaw was found in the way ntpd processed 'ntpdc reslist' commands that queried restriction lists with a large amount of entries. A remote attacker could potentially use this flaw to crash ntpd. (CVE-2015-7977) * A stack-based buffer overflow flaw was found in the way ntpd processed 'ntpdc reslist' commands that queried restriction lists with a large amount of entries. A remote attacker could use this flaw to crash ntpd. (CVE-2015-7978) * It was found that when NTP was configured in broadcast mode, a remote attacker could broadcast packets with bad authentication to all clients. The clients, upon receiving the malformed packets, would break the association with the broadcast server, causing them to become out of sync over a longer period of time. (CVE-2015-7979) * It was found that ntpd could crash due to an uninitialized variable when processing malformed logconfig configuration commands. (CVE-2015-5194) * It was found that ntpd would exit with a segmentation fault when a statistics type that was not enabled during compilation (e.g. timingstats) was referenced by the statistics or filegen configuration command. (CVE-2015-5195) * It was found that NTP's :config command could be used to set the pidfile and driftfile paths without any restrictions. A remote attacker could use this flaw to overwrite a file on the file system with a file containing the pid of the ntpd process (immediately) or the current estimated drift of the system clock (in hourly intervals). (CVE-2015-5196, CVE-2015-7703) * It was discovered that the sntp utility could become unresponsive due to being caught in an infinite loop when processing a crafted NTP packet. (CVE-2015-5219) * A flaw was found in the way NTP verified trusted keys during symmetric key authentication. An authenticated client (A) could use this flaw to modify a packet sent between a server (B) and a client (C) using a key that is different from the one known to the client (A). (CVE-2015-7974) * A flaw was found in the way the ntpq client processed certain incoming packets in a loop in the getresponse() function. A remote attacker could potentially use this flaw to crash an ntpq client instance. (CVE-2015-8158) The CVE-2015-5219 and CVE-2015-7703 issues were discovered by Miroslav Lichvar (Red Hat).

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

    description Several vulnerabilities were discovered in the Network Time Protocol daemon and utility programs : CVE-2015-7974 Matt Street discovered that insufficient key validation allows impersonation attacks between authenticated peers. CVE-2015-7977 / CVE-2015-7978 Stephen Gray discovered that a NULL pointer dereference and a buffer overflow in the handling of 'ntpdc reslist' commands may result in denial of service. CVE-2015-7979 Aanchal Malhotra discovered that if NTP is configured for broadcast mode, an attacker can send malformed authentication packets which break associations with the server for other broadcast clients. CVE-2015-8138 Matthew van Gundy and Jonathan Gardner discovered that missing validation of origin timestamps in ntpd clients may result in denial of service. CVE-2015-8158 Jonathan Gardner discovered that missing input sanitising in ntpq may result in denial of service. CVE-2016-1547 Stephen Gray and Matthew van Gundy discovered that incorrect handling of crypto NAK packets my result in denial of service. CVE-2016-1548 Jonathan Gardner and Miroslav Lichvar discovered that ntpd clients could be forced to change from basic client/server mode to interleaved symmetric mode, preventing time synchronisation. CVE-2016-1550 Matthew van Gundy, Stephen Gray and Loganaden Velvindron discovered that timing leaks in the the packet authentication code could result in recovery of a message digest. CVE-2016-2516 Yihan Lian discovered that duplicate IPs on 'unconfig' directives will trigger an assert. CVE-2016-2518 Yihan Lian discovered that an OOB memory access could potentially crash ntpd. For Debian 7 'Wheezy', these problems have been fixed in version 1:4.2.6.p5+dfsg-2+deb7u7. We recommend that you upgrade your ntp packages.

    description The version of the remote NTP server is 3.x or 4.x prior to 4.2.8p6. It is, therefore, affected by the following vulnerabilities : - A flaw exists in the receive() function due to the use of authenticated broadcast mode. A man-in-the-middle attacker can exploit this to conduct a replay attack. (CVE-2015-7973) - A time serving flaw exists in the trusted key system due to improper key checks. An authenticated, remote attacker can exploit this to perform impersonation attacks between authenticated peers. (CVE-2015-7974) - An overflow condition exists in the nextvar() function due to improper validation of user-supplied input. A local attacker can exploit this to cause a buffer overflow, resulting in a denial of service condition. (CVE-2015-7975) - A flaw exists in ntp_control.c due to improper filtering of special characters in filenames by the saveconfig command. An authenticated, remote attacker can exploit this to inject arbitrary content. (CVE-2015-7976) - A NULL pointer dereference flaw exists in ntp_request.c that is triggered when handling ntpdc relist commands. A remote attacker can exploit this, via a specially crafted request, to crash the service, resulting in a denial of service condition. (CVE-2015-7977) - A flaw exists in ntpdc that is triggered during the handling of the relist command. A remote attacker can exploit this, via recursive traversals of the restriction list, to exhaust available space on the call stack, resulting in a denial of service condition. CVE-2015-7978) - An unspecified flaw exists in authenticated broadcast mode. A remote attacker can exploit this, via specially crafted packets, to cause a denial of service condition. (CVE-2015-7979) - A flaw exists in the receive() function that allows packets with an origin timestamp of zero to bypass security checks. A remote attacker can exploit this to spoof arbitrary content. (CVE-2015-8138) - A flaw exists in ntpq and ntpdc that allows a remote attacker to disclose sensitive information in timestamps. (CVE-2015-8139) - A flaw exists in the ntpq protocol that is triggered during the handling of an improper sequence of numbers. A man-in-the-middle attacker can exploit this to conduct a replay attack. (CVE-2015-8140) - A flaw exists in the ntpq client that is triggered when handling packets that cause a loop in the getresponse() function. A remote attacker can exploit this to cause an infinite loop, resulting in a denial of service condition. (CVE-2015-8158)

    description NTPv3 and NTPv4 are vulnerable to : http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-7974 NTP could allow a remote authenticated attacker to conduct spoofing attacks, caused by a missing key check. An attacker could exploit this vulnerability to impersonate a peer. NTP could allow a local attacker to bypass security restrictions, caused by the failure to use a constant-time memory comparison function when validating the authentication digest on incoming packets. By sending a specially crafted packet with an authentication payload, an attacker could exploit this vulnerability to conduct a timing attack to compute the value of the valid authentication digest. While the majority OSes implement martian packet filtering in their network stack, at least regarding 127.0.0.0/8, a rare few will allow packets claiming to be from 127.0.0.0/8 that arrive over physical network. On these OSes, if ntpd is configured to use a reference clock an attacker can inject packets over the network that look like they are coming from that reference clock. If ntpd was expressly configured to allow for remote configuration, a malicious user who knows the controlkey for ntpq or the requestkey for ntpdc (if mode7 is expressly enabled) can create a session with ntpd and then send a crafted packet to ntpd that will change the value of the trustedkey, controlkey, or requestkey to a value that will prevent any subsequent authentication with ntpd until ntpd is restarted. NTP is vulnerable to a denial of service, caused by an error when using a specially crafted packet to create a peer association with hmode > 7. An attacker could exploit this vulnerability to cause the MATCH_ASSOC() function to trigger an out-of-bounds read. NTP is vulnerable to a denial of service, caused by the failure to always check the ctl_getitem() function return value. By sending an overly large value, an attacker could exploit this vulnerability to cause a denial of service. NTP is vulnerable to a denial of service, caused by the demobilization of a preemptable client association. By sending specially crafted crypto NAK packets, an attacker could exploit this vulnerability to cause a denial of service. NTP is vulnerable to a denial of service, caused by the improper handling of packets. By sending specially crafted CRYPTO_NAK packets, an attacker could exploit this vulnerability to cause ntpd to crash. NTP is vulnerable to a denial of service, caused by the improper handling of packets. By sending specially crafted CRYPTO_NAK packets to an ephemeral peer target prior to a response being sent, a remote attacker could exploit this vulnerability to demobilize the ephemeral association.

By sending spoofed server packets with correct origin timestamps, a remote attacker could exploit this vulnerability to cause a false leap indication to be set. NTP is vulnerable to a denial of service, caused by the improper handling of packets. By sending spoofed CRYPTO_NAK or a bad MAC packets with correct origin timestamps, a remote attacker could exploit this vulnerability to cause the autokey association to reset.

    description It was discovered that ntpd as a client did not correctly check the originate timestamp in received packets. A remote attacker could use this flaw to send a crafted packet to an ntpd client that would effectively disable synchronization with the server, or push arbitrary offset/delay measurements to modify the time on the client. (CVE-2015-8138) A NULL pointer dereference flaw was found in the way ntpd processed 'ntpdc reslist' commands that queried restriction lists with a large amount of entries. A remote attacker could use this flaw to crash the ntpd process. (CVE-2015-7977) It was found that NTP does not verify peer associations of symmetric keys when authenticating packets, which might allow remote attackers to conduct impersonation attacks via an arbitrary trusted key. (CVE-2015-7974) A stack-based buffer overflow was found in the way ntpd processed 'ntpdc reslist' commands that queried restriction lists with a large amount of entries. A remote attacker could use this flaw to crash the ntpd process. (CVE-2015-7978) It was found that when NTP is configured in broadcast mode, an off-path attacker could broadcast packets with bad authentication (wrong key, mismatched key, incorrect MAC, etc) to all clients. The clients, upon receiving the malformed packets, would break the association with the broadcast server. This could cause the time on affected clients to become out of sync over a longer period of time. (CVE-2015-7979) A flaw was found in the way the ntpq client certain processed incoming packets in a loop in the getresponse() function. A remote attacker could potentially use this flaw to crash an ntpq client instance. (CVE-2015-8158) A flaw was found in ntpd that allows remote attackers to cause a denial of service (ephemeral-association demobilization) by sending a spoofed crypto-NAK packet with incorrect authentication data at a certain time. (CVE-2016-4953) (Updated 2016-10-18: CVE-2016-4953 was fixed in this release but was not previously part of this errata.)
