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...
