CVE-2018-7184

CVE-2018-7184 affects ntpd 4.2.8p4 through 4.2.8p10, where a zero-origin timestamp in certain packets can disrupt the association and cause DoS. This is described as a result of an incomplete fix for CVE-2015-7704. Remediation available: upgrade to ntpd 4.2.8p11 or later; several advisories (e.g....

CVE-2018-7182

The CVE-2018-7182 vulnerability affects ntp ntpd versions 4.2.8p6–4.2.8p10, where the ctl_getitem() function can read past the end of its buffer. A remote attacker can send a crafted mode 6 packet to trigger an out-of-bounds read, causing denial of service. Public references include Exploit-DB’s ...

CVE-2018-7182

The ctlgetitem method in ntpd in ntp-4.2.8p6 before 4.2.8p11 allows remote attackers to cause a denial of service out-of-bounds read via a crafted mode 6 packet with a ntpd instance from 4.2.8p6 through 4.2.8p10...

CVE-2018-7184

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 contents of the packet as the mos...

CVE-2018-7170

ntpd in ntp 4.2.x before 4.2.8p7 and 4.3.x before 4.3.92 allows authenticated users that know the private symmetric key to create arbitrarily-many ephemeral associations in order to win the clock selection of ntpd and modify a victim's clock via a Sybil attack. This issue exists because of an...

CVE-2018-7170

A flaw was found in ntpd making it vulnerable to Sybil attacks. An authenticated attacker could target systems configured to use a trusted key in certain configurations and to create an arbitrary number of associations and subsequently modify a victim's clock...

Network Time Protocol Ephemeral Association Time Spoofing Vulnerability(CVE-2016-1549)

SUMMARY ntpd is vulnerable to Sybil attacks. A malicious authenticated peer can create arbitrarily-many ephemeral associations in order to win ntpd's clock selection algorithm and modify a victim's clock. TESTED VERSIONS NTP 4.2.8p3 NTP 4.2.8p4 NTPsec 3e160db8dc248a0bcb053b56a80167dc742d2b74 NTPs...

Network Time Protocol ntpd Reference Clock Impersonation Vulnerability(CVE-2016-1551)

SUMMARY ntpd relies on the underlying operating system to protect it from requests that impersonate reference clocks. Because reference clocks are treated like other peers and stored in the same structure, any packet with a source ip address of a reference clock 127.127.1.1 for example that reach...

Network Time Protocol Trap Crash Denial of Service Vulnerability(CVE-2016-9311)

Summary An exploitable denial of service vulnerability exists in the trap functionality of ntpd. If an ntpd instance is configured to send traps, a specially crafted network packet can be used to cause a null pointer dereference resulting in a denial of service. This vulnerability can be triggere...
