K15928: Network Time Protocol vulnerability CVE-2009-1252

Security Advisory Description Stack-based buffer overflow in the cryptorecv function in ntpcrypto.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...

K13540723: NTP vulnerability CVE-2018-7184

Security Advisory Description ntpd in ntp 4.2.8p4 before 4.2.8p11 drops bad packets before updating the "received" timestamp, which allows remote attackers to cause a denial of service disruption by sending a packet with a zero-origin timestamp causing the association to reset and setting the...

K09940637: NTP vulnerability CVE-2019-11331

Security Advisory Description Network Time Protocol NTP, as specified in RFC 5905, uses port 123 even for modes where a fixed port number is not required, which makes it easier for remote attackers to conduct off-path attacks. CVE-2019-11331 Impact Using an off-path attack not a man-in-the-middle...

SUSE CVE-2004-0657

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...

SUSE CVE-2009-0021

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 EVPVerifyFinal 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...

SUSE CVE-2009-0159

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...

SUSE CVE-2009-3563

ntprequest.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 MODEPRIVATE to send a spoofed 1 request or 2 response packet that triggers a continuous exchange of MODEPRIVATE error responses between two NTP daemon...

SUSE CVE-2013-5211

The monlist feature in ntprequest.c in ntpd in NTP before 4.2.7p26 allows remote attackers to cause a denial of service traffic amplification via forged 1 REQMONGETLIST or 2 REQMONGETLIST1 requests, as exploited in the wild in December 2013...

SUSE CVE-2014-5209

An Information Disclosure vulnerability exists in NTP 4.2.7p25 private mode 6/7 messages via a GETRESTRICT control message, which could let a malicious user obtain sensitive information...

SUSE CVE-2014-9293

The configauth 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...

SUSE CVE-2014-9294

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...

SUSE CVE-2014-9296

The receive function in ntpproto.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...

SUSE CVE-2014-9295

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 cryptorecv function when the Autokey Authentication feature is used, 2 the ctlputdata function, and 3 the configure function...

SUSE CVE-2014-9751

The readnetworkpacket function in ntpio.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...

SUSE CVE-2014-9750

ntpcrypto.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...

SUSE CVE-2015-1799

The symmetric-key feature in the receive function in ntpproto.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...

SUSE CVE-2015-1853

chrony before 1.31.1 does not properly protect state variables in authenticated symmetric NTP associations, which allows remote attackers with knowledge of NTP peering to cause a denial of service inability to synchronize via random timestamps in crafted NTP data packets...

SUSE CVE-2015-5194

The logconfigcommand function in ntpparser.y in ntpd in NTP before 4.2.7p42 allows remote attackers to cause a denial of service ntpd crash via crafted logconfig commands...

SUSE CVE-2015-5195
