CVE-2020-11868

A flaw was found in the Network Time Protocol NTP, where a security issue exists that allows an off-path attacker to prevent the Network Time Protocol daemon ntpd from synchronizing with NTP servers not using authentication. A server mode packet with a spoofed source address sent to the client nt...

Name of the Vulnerable Software and Affected Versions: ntp versions 4.2.8 through 4.2.8p14 ntp versions 4.3.x through 4.3.100 Description: The issue allows an off-path attacker to block unauthenticated synchronization via a server mode packet with a spoofed source IP address. This is because...

DNS Spoofing

GNU C Library is vulnerable to DNS spoofing attacks. A remote unauthenticated attacker could potentially simplify off-path DNS spoofing attacks due to IP fragmentation. This affects some unknown processing of the component EDNS Support...

CVE-2019-11331

Network Time Protocol NTP, as specified in RFC 5905, uses port 123 even for modes where a fixed port number is not required, which makes it easier for remote attackers to conduct off-path attacks. Mitigation On Red Hat Enterprise Linux 6 and later, switching from ntp to chrony is recommended. Amo...
