MGASA-2020-0212 Updated ntp packages fix security vulnerability

The updated packages fix security vulnerabilities including: ntpd in ntp before 4.2.8p14 and 4.3.x before 4.3.100 allows an off-path attacker to block unauthenticated synchronization via a server mode packet with a spoofed source IP address, because transmissions are rescheduled even when a packe...

UBUNTU-CVE-2020-11868

ntpd in ntp before 4.2.8p14 and 4.3.x before 4.3.100 allows an off-path attacker to block unauthenticated synchronization via a server mode packet with a spoofed source IP address, because transmissions are rescheduled even when a packet lacks a valid origin timestamp...

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...

Path traversal

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...

Updated glibc packages fix security vulnerabilities

The DNS stub resolver in the GNU C Library aka glibc or libc6 before version 2.26, when EDNS support is enabled, will solicit large UDP responses from name servers, potentially simplifying off-path DNS spoofing attacks due to IP fragmentation.CVE-2017-12132, CVE-2017-12133. The GNU C Library aka...

GNU C Library DNS Spoofing Vulnerability

The GNU C Library aka glibc, libc6 is an open-source, free C language compiler released under the LGPL license. A security vulnerability exists in the DNS stub resolver in versions of the GNU C Library prior to 2.26. An attacker can exploit this vulnerability to perform an off-path DNS spoofing...

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...

kernel: challenge ACK counter information disclosure.

It was found that the RFC 5961 challenge ACK rate limiting as implemented in the Linux kernel's networking subsystem allowed an off-path attacker to leak certain information about a given connection by creating congestion on the global challenge ACK rate limit counter and then measuring the chang...

Serious TCP Bug in Linux Systems Allows Traffic Hijacking

A serious vulnerability in the TCP implementation in Linux systems deployed since 2012 version 3.6 of the Linux kernel can be used by attackers to identify hosts communicating over the protocol and ultimately attack that traffic. Researchers from the University of California, Riverside and the U....
