DEBIAN-CVE-2016-7429

NTP before 4.2.8p9 changes the peer structure to the interface it receives the response from a source, which allows remote attackers to cause a denial of service prevent communication with a source by sending a response for a source to an interface the source does not use...

UBUNTU-CVE-2016-7426

NTP before 4.2.8p9 rate limits responses received from the configured sources when rate limiting for all associations is enabled, which allows remote attackers to cause a denial of service prevent responses from the sources by sending responses with a spoofed source address...

Network Time Protocol Windows Daemon getEndptFromIoCtx Denial of Service (CVE-2016-9312)

A denial of service vulnerability has been reported in the Windows port of Network Time Foundation's NTP Daemon. The vulnerability is due to insufficient error handling when receiving large UDP packets. A remote, unauthenticated attacker can exploit this vulnerability by sending a large UDP packe...

DEBIAN-CVE-2016-1550

An exploitable vulnerability exists in the message authentication functionality of libntp in ntp 4.2.8p4 and NTPSec a5fb34b9cc89b92a8fef2f459004865c93bb7f92. An attacker can send a series of crafted messages to attempt to recover the message digest key...

UBUNTU-CVE-2016-1549

A malicious authenticated peer can create arbitrarily-many ephemeral associations in order to win the clock selection algorithm in ntpd in NTP 4.2.8p4 and earlier and NTPsec 3e160db8dc248a0bcb053b56a80167dc742d2b74 and a5fb34b9cc89b92a8fef2f459004865c93bb7f92 and modify a victim's clock...

DEBIAN-CVE-2015-7848

An integer overflow can occur in NTP-dev.4.3.70 leading to an out-of-bounds memory copy operation when processing a specially crafted private mode packet. The crafted packet needs to have the correct message authentication code and a valid timestamp. When processed by the NTP daemon, it leads to ...

DEBIAN-CVE-2016-1547

An off-path attacker can cause a preemptible client association to be demobilized in NTP 4.2.8p4 and earlier and NTPSec a5fb34b9cc89b92a8fef2f459004865c93bb7f92 by sending a crypto NAK packet to a victim client with a spoofed source address of an existing associated peer. This is true even if...
