Debian Security Advisory DSA 3223-1 (ntp - security update)

Multiple vulnerabilities were discovered in ntp, an implementation of the Network Time Protocol: CVE-2015-1798 When configured to use a symmetric key with an NTP peer, ntpd would accept packets without MAC as if they had a valid MAC. This could allow a remote attacker to bypass the packet...

Network Time Protocol Daemon MAC Checking Failure Authentication Bypass Vulnerability

A vulnerability in the Network Time Protocol NTP daemon could allow an unauthenticated, adjacent attacker to bypass authentication mechanisms and access an affected system. The vulnerability is due to incorrect validation of the message authentication code MAC field. An attacker could exploit thi...

Network Time Protocol Daemon Symmetric Mode Packet Processing Denial of Service Vulnerability

A vulnerability in ntpd could allow an unauthenticated, adjacent attacker to cause a denial of service DoS condition on an affected system. The vulnerability is due to improper processing of Network Time Protocol NTP packets when handling symmetric key authentication failures. An attacker could...

NTP Symmetric Key Authentication Security Vulnerabilities Patched

NTP, the much maligned protocol abused in a number of high volume DDoS attacks a year ago, is suffering from newly patched vulnerabilities that could allow an attacker to send unauthenticated packets to a client that would be executed. The Department of Homeland Security and CERT at the Software...
