USN-4229-1 fixed a vulnerability in NTP. This update provides the corresponding update for Ubuntu 18.04 ESM. Original advisory details: It was discovered that ntpq and ntpdc incorrectly handled some arguments. An attacker could possibly use this issue to cause ntpq or ntpdc to crash, execute...
Low: ntp
Issue Overview: The ntpq and ntpdc command-line utilities that are part of ntp package are vulnerable to stack-based buffer overflow via crafted hostname. Applications using these vulnerable utilities with an untrusted input may be potentially exploited, resulting in a crash or arbitrary code...
CVE-2018-12327
The ntpq and ntpdc command-line utilities that are part of ntp package are vulnerable to stack-based buffer overflow via crafted hostname. Applications using these vulnerable utilities with an untrusted input may be potentially exploited, resulting in a crash or arbitrary code execution under...
EulerOS Virtualization for ARM 64 3.0.1.0 : ntp (EulerOS-SA-2019-1398)
According to the version of the ntp packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerability : - The ntpq and ntpdc command-line utilities that are part of ntp package are vulnerable to stack-based buffer overflow via...
Denial Of Service (DoS)
ntp is vulnerable to denial of service. 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...
Weak Authentication
The Network Time Protocol NTP is used to synchronize a computer's time with a referenced time source. Multiple buffer overflow flaws were discovered in ntpd's cryptorecv, ctlputdata, and configure functions. A remote attacker could use either of these flaws to send a specially crafted request...

Amazon Linux AMI : ntp (ALAS-2018-1083)
ntpd in ntp 4.2.x before 4.2.8p7 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 incomplete fix for...
CVE-2018-12327
Stack-based buffer overflow in ntpq and ntpdc of NTP version 4.2.8p11 allows an attacker to achieve code execution or escalate to higher privileges via a long string as the argument for an IPv4 or IPv6 command-line parameter. NOTE: It is unclear whether there are any common situations in which nt...

CVE-2015-7978: Uncontrolled Resource Consumption
NTP before 4.2.8p6 and 4.3.0 before 4.3.90 allows a remote attackers to cause a denial of service stack exhaustion via an ntpdc relist command, which triggers recursive traversal of the restriction list...
AIX NTP v4 Advisory : ntp_advisory6.asc (IV83983) (IV83992)
The version of NTP installed on the remote AIX host is 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 NULL pointer...
Network Time Protocol ntpq and ntpdc Origin Timestamp Disclosure Vulnerability
CERT VU357792 Summary To prevent off-path attackers from impersonating legitimate peers, clients require that the origin timestamp in a received response packet match the transmit timestamp from its last request to a given peer. Under assumption that only the recipient of the request packet will...
Network Time Protocol ntpq and ntpdc Infinite Loop Vulnerability
CERT VU357792 Summary ntpq processes incoming packets in a loop in getresponse. The loop’s only stopping conditions are receiving a complete and correct response or hitting a small number of error conditions. If the packet contains incorrect values that don’t trigger one of the error conditions,...
