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-2016-1549

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 ...
