CVE-2015-5194 6 Canonical, Debian, Fedoraproject and 3 more 14 Ubuntu Linux, Debian Linux, Fedora and 11 more 2024-11-21 N/A
The log_config_command function in ntp_parser.y in ntpd in NTP before 4.2.7p42 allows remote attackers to cause a denial of service (ntpd crash) via crafted logconfig commands.
CVE-2015-5146 3 Debian, Fedoraproject, Ntp 3 Debian Linux, Fedora, Ntp 2024-11-21 N/A
ntpd in ntp before 4.2.8p3 with remote configuration enabled allows remote authenticated users with knowledge of the configuration password and access to a computer entrusted to perform remote configuration to cause a denial of service (service crash) via a NULL byte in a crafted configuration directive packet.
CVE-2015-3405 7 Debian, Fedoraproject, Ntp and 4 more 14 Debian Linux, Fedora, Ntp and 11 more 2024-11-21 N/A
ntp-keygen in ntp 4.2.8px before 4.2.8p2-RC2 and 4.3.x before 4.3.12 does not generate MD5 keys with sufficient entropy on big endian machines when the lowest order byte of the temp variable is between 0x20 and 0x7f and not #, which might allow remote attackers to obtain the value of generated MD5 keys via a brute force attack with the 93 possible keys.
CVE-2015-1799 2 Ntp, Redhat 2 Ntp, Enterprise Linux 2024-11-21 N/A
The symmetric-key feature in the receive function in ntp_proto.c in ntpd in NTP 3.x and 4.x before 4.2.8p2 performs state-variable updates upon receiving certain invalid packets, which makes it easier for man-in-the-middle attackers to cause a denial of service (synchronization loss) by spoofing the source IP address of a peer.
CVE-2015-1798 2 Ntp, Redhat 2 Ntp, Enterprise Linux 2024-11-21 N/A
The symmetric-key feature in the receive function in ntp_proto.c in ntpd in NTP 4.x before 4.2.8p2 requires a correct MAC only if the MAC field has a nonzero length, which makes it easier for man-in-the-middle attackers to spoof packets by omitting the MAC.
CVE-2014-9751 6 Apple, Debian, Linux and 3 more 9 Macos, Debian Linux, Linux Kernel and 6 more 2024-11-21 N/A
The read_network_packet function in ntp_io.c in ntpd in NTP 4.x before 4.2.8p1 on Linux and OS X does not properly determine whether a source IP address is an IPv6 loopback address, which makes it easier for remote attackers to spoof restricted packets, and read or write to the runtime state, by leveraging the ability to reach the ntpd machine's network interface with a packet from the ::1 address.
CVE-2014-9750 4 Debian, Ntp, Oracle and 1 more 7 Debian Linux, Ntp, Linux and 4 more 2024-11-21 N/A
ntp_crypto.c in ntpd in NTP 4.x before 4.2.8p1, when Autokey Authentication is enabled, allows remote attackers to obtain sensitive information from process memory or cause a denial of service (daemon crash) via a packet containing an extension field with an invalid value for the length of its value field.
CVE-2014-9296 2 Ntp, Redhat 3 Ntp, Enterprise Linux, Rhel Eus 2024-11-21 N/A
The receive function in ntp_proto.c in ntpd in NTP before 4.2.8 continues to execute after detecting a certain authentication error, which might allow remote attackers to trigger an unintended association change via crafted packets.
CVE-2014-9295 2 Ntp, Redhat 3 Ntp, Enterprise Linux, Rhel Eus 2024-11-21 N/A
Multiple stack-based buffer overflows in ntpd in NTP before 4.2.8 allow remote attackers to execute arbitrary code via a crafted packet, related to (1) the crypto_recv function when the Autokey Authentication feature is used, (2) the ctl_putdata function, and (3) the configure function.
CVE-2014-9294 2 Ntp, Redhat 3 Ntp, Enterprise Linux, Rhel Eus 2024-11-21 N/A
util/ntp-keygen.c in ntp-keygen in NTP before 4.2.7p230 uses a weak RNG seed, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via a brute-force attack.
CVE-2014-9293 2 Ntp, Redhat 3 Ntp, Enterprise Linux, Rhel Eus 2024-11-21 N/A
The config_auth function in ntpd in NTP before 4.2.7p11, when an auth key is not configured, improperly generates a key, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via a brute-force attack.
CVE-2014-5209 2 F5, Ntp 25 Big-ip Access Policy Manager, Big-ip Advanced Firewall Manager, Big-ip Analytics and 22 more 2024-11-21 5.3 Medium
An Information Disclosure vulnerability exists in NTP 4.2.7p25 private (mode 6/7) messages via a GET_RESTRICT control message, which could let a malicious user obtain sensitive information.
CVE-2013-5211 3 Ntp, Opensuse, Oracle 3 Ntp, Opensuse, Linux 2024-11-21 N/A
The monlist feature in ntp_request.c in ntpd in NTP before 4.2.7p26 allows remote attackers to cause a denial of service (traffic amplification) via forged (1) REQ_MON_GETLIST or (2) REQ_MON_GETLIST_1 requests, as exploited in the wild in December 2013.
CVE-2009-3563 2 Ntp, Redhat 2 Ntp, Enterprise Linux 2024-11-21 N/A
ntp_request.c in ntpd in NTP before 4.2.4p8, and 4.2.5, allows remote attackers to cause a denial of service (CPU and bandwidth consumption) by using MODE_PRIVATE to send a spoofed (1) request or (2) response packet that triggers a continuous exchange of MODE_PRIVATE error responses between two NTP daemons.
CVE-2009-1252 2 Ntp, Redhat 3 Ntp, Enterprise Linux, Rhel Eus 2024-11-21 N/A
Stack-based buffer overflow in the crypto_recv function in ntp_crypto.c in ntpd in NTP before 4.2.4p7 and 4.2.5 before 4.2.5p74, when OpenSSL and autokey are enabled, allows remote attackers to execute arbitrary code via a crafted packet containing an extension field.
CVE-2009-0159 2 Ntp, Redhat 3 Ntp, Enterprise Linux, Rhel Eus 2024-11-21 N/A
Stack-based buffer overflow in the cookedprint function in ntpq/ntpq.c in ntpq in NTP before 4.2.4p7-RC2 allows remote NTP servers to execute arbitrary code via a crafted response.
CVE-2009-0021 2 Ntp, Redhat 2 Ntp, Enterprise Linux 2024-11-21 N/A
NTP 4.2.4 before 4.2.4p5 and 4.2.5 before 4.2.5p150 does not properly check the return value from the OpenSSL EVP_VerifyFinal function, which allows remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature for DSA and ECDSA keys, a similar vulnerability to CVE-2008-5077.
CVE-2004-0657 2 Hp, Ntp 2 Tru64 Unix, Ntp 2024-11-21 7.1 High
Integer overflow in the NTP daemon (NTPd) before 4.0 causes the NTP server to return the wrong date/time offset when a client requests a date/time that is more than 34 years away from the server's time.
