NTP Denial of Service Vulnerability (CNVD-2015-07019)
NTP Network Time Protocol is a network protocol that synchronizes the clocks of two computers by exchanging packets. A security vulnerability exists in NTP versions prior to 4.2.8p4 and 4.3.x prior to 4.3.77. due to the program failing to properly check packet length. An attacker could exploit th...

NTP Network Time Protocol is a network protocol that synchronizes the clocks of two computers by exchanging packets. A security vulnerability exists in NTP versions prior to 4.2.8p4 and 4.3.x prior to 4.3.77. due to the client failing to properly validate the timestamp field in a Kiss-of-Death...
NTP Arbitrary File Overwrite Vulnerability
NTP Network Time Protocol is a network protocol that synchronizes the clocks of two computers by exchanging packets. A security vulnerability exists in NTP versions prior to 4.2.8p4 and 4.3.x prior to 4.3.77. Since the program allows unlimited pidfile and driftfile paths to be set using the :conf...
NTP Denial of Service Vulnerability (CNVD-2015-07021)
NTP Network Time Protocol is a network protocol that synchronizes the clocks of two computers by exchanging packets. A security vulnerability exists in NTP versions prior to 4.2.8p4 and 4.3.x prior to 4.3.77. When ntpd is configured to use autokey, an attacker can exploit this vulnerability by...
NTP Denial of Service Vulnerability (CNVD-2015-07022)
NTP Network Time Protocol is a network protocol that synchronizes the clocks of two computers by exchanging packets. A security vulnerability exists in NTP versions prior to 4.2.8p4 and 4.3.x prior to 4.3.77. Due to the program failing to properly use authentication and restriction mechanisms to...
NTP Directory Traversal Vulnerability
NTP Network Time Protocol is a network protocol that synchronizes the clocks of two computers by exchanging packets. A security vulnerability exists in NTP versions prior to 4.2.8p4 and 4.3.x prior to 4.3.77. A remote attacker can exploit this vulnerability by sending NTP packets to overwrite the...
NTP Memory Corruption Vulnerability
NTP Network Time Protocol is a network protocol that synchronizes the clocks of two computers by exchanging packets. A security vulnerability exists in NTP versions prior to 4.2.8p4 and 4.3.x prior to 4.3.77. When the program is allowed to be configured remotely, an attacker could exploit the...
NTP Denial of Service Vulnerability (CNVD-2015-07024)
NTP Network Time Protocol is a network protocol that synchronizes the clocks of two computers by exchanging packets. A security vulnerability exists in NTP versions prior to 4.2.8p4 and 4.3.x prior to 4.3.77. When the program allows remote configuration, an attacker can exploit the vulnerability ...
Network Time Protocol Daemon (ntpd) 3.x / 4.x < 4.2.8p4 Multiple Vulnerabilities
The version of the remote NTP server is 3.x or 4.x prior to 4.2.8p4. It is, therefore, affected by the following vulnerabilities : - A flaw exists in the ntpcrypto.c file due to improper validation of the 'vallen' value in extension fields. An unauthenticated, remote attacker can exploit this, vi...

ntp: MITM attacker can force ntpd to make a step larger than the panic threshold
It was found that ntpd did not correctly implement the threshold limitation for the '-g' option, which is used to set the time without any restrictions. A man-in-the-middle attacker able to intercept NTP traffic between a connecting client and an NTP server could use this flaw to force that clien...
ntp: disabling synchronization via crafted KoD packet
It was discovered that ntpd as a client did not correctly check timestamps in Kiss-of-Death packets. A remote attacker could use this flaw to send a crafted Kiss-of-Death packet to an ntpd client that would increase the client's polling interval value, and effectively disable synchronization with...
