1 CVE-2015-1799 17 DoS 2015-04-08 2015-04-16
4.3
None Local Network Medium Not required None Partial Partial
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.
2 CVE-2015-1798 17 2015-04-08 2015-04-14
1.8
None Local Network High Not required None Partial None
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.
3 CVE-2014-9296 17 2014-12-19 2015-03-25
5.0
None Remote Low Not required None None Partial
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.
4 CVE-2014-9295 119 Exec Code Overflow 2014-12-19 2015-03-25
7.5
None Remote Low Not required Partial Partial Partial
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.
5 CVE-2014-9294 2014-12-19 2015-03-25
7.5
None Remote Low Not required Partial Partial Partial
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.
6 CVE-2014-9293 2014-12-19 2015-03-25
7.5
None Remote Low Not required Partial Partial Partial
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.
7 CVE-2013-5211 20 DoS 2014-01-02 2014-12-02
5.0
None Remote Low Not required None None Partial
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.
8 CVE-2009-3563 DoS 2009-12-09 2013-12-04
6.4
None Remote Low Not required None Partial Partial
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.
9 CVE-2009-1252 119 Exec Code Overflow 2009-05-19 2010-08-21
6.8
None Remote Medium Not required Partial Partial Partial
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.
10 CVE-2009-0159 119 Exec Code Overflow 2009-04-14 2013-12-04
6.8
User Remote Medium Not required Partial Partial Partial
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.
11 CVE-2009-0021 287 Bypass 2009-01-07 2012-10-30
5.0
None Remote Low Not required Partial None None
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.
12 CVE-2004-0657 Overflow 2004-08-06 2008-09-05
5.0
None Remote Low Not required None Partial None
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.
