Nmap is a utility for port scanning large networks, although it works fine for single hosts. Sometimes you need speed, other times you may need stealth. In some cases, bypassing firewalls may be required. Not to mention the fact that you may want to scan different protocols (UDP, TCP, ICMP, etc.). Nmap supports Vanilla TCP connect() scanning, TCP SYN (half open) scanning, TCP FIN, Xmas, or NULL (stealth) scanning, TCP ftp proxy (bounce attack) scanning, SYN/FIN scanning using IP fragments (bypasses some packet filters), TCP ACK and Window scanning, UDP raw ICMP port unreachable scanning, ICMP scanning (ping-sweep), TCP Ping scanning, Direct (non portmapper) RPC scanning, Remote OS Identification by TCP/IP Fingerprinting, and Reverse-ident scanning. Nmap also supports a number of performance and reliability features such as dynamic delay time calculations, packet timeout and retransmission, parallel port scanning, detection of down hosts via parallel pings.

Debian Linux Security Advisory 5664-1 - Jetty 9 is a Java based web server and servlet engine. It was discovered that remote attackers may leave many HTTP/2 connections in ESTABLISHED state (not closed), TCP congested and idle. Eventually the server will stop accepting new connections from valid clients which can cause a denial of service.

The PsyRAT 0.01 malware listens on random high TCP ports 53297, 53211, 532116 and so forth. Connecting to an infected host returns a logon prompt for PASS. However, you can enter anything or nothing at all and execute commands made available by the backdoor.

GNUnet is a peer-to-peer framework with focus on providing security. All peer-to-peer messages in the network are confidential and authenticated. The framework provides a transport abstraction layer and can currently encapsulate the network traffic in UDP (IPv4 and IPv6), TCP (IPv4 and IPv6), HTTP, or SMTP messages. GNUnet supports accounting to provide contributing nodes with better service. The primary service build on top of the framework is anonymous file sharing.

Services that are running and bound to the loopback interface on the Artica Proxy version 4.50 are accessible through the proxy service. In particular, the tailon service is running as the root user, is bound to the loopback interface, and is listening on TCP port 7050. Using the tailon service, the contents of any file on the Artica Proxy can be viewed.

An issue was discovered in Contiki-NG tinyDTLS versions through 2018-08-30. DTLS servers allow remote attackers to reuse the same epoch number within two times the TCP maximum segment lifetime, which is prohibited in RFC6347. This vulnerability allows remote attackers to obtain sensitive application (data of connected clients).

Ubuntu Security Notice 6497-1 - Maxim Levitsky discovered that the KVM nested virtualization implementation for AMD processors in the Linux kernel did not properly handle x2AVIC MSRs. An attacker in a guest VM could use this to cause a denial of service. Alon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel did not properly handle queue initialization failures in certain situations, leading to a use-after-free vulnerability. A remote attacker could use this to cause a denial of service or possibly execute arbitrary code.

Samhain is a file system integrity checker that can be used as a client/server application for centralized monitoring of networked hosts. Databases and configuration files can be stored on the server. Databases, logs, and config files can be signed for tamper resistance. In addition to forwarding reports to the log server via authenticated TCP/IP connections, several other logging facilities (e-mail, console, and syslog) are available. Tested on Linux, AIX, HP-UX, Unixware, Sun and Solaris.

Simple Packet Sender (SPS) is a Linux packet crafting tool. It supports IPv4, IPv6 (but not extension headers yet), and tunneling IPv6 over IPv4. Written in C on Linux with GUI built using GTK+. Both source and binaries are included. Features include packet crafting and sending one, multiple, or flooding packets of type TCP, ICMP, or UDP. All values within ethernet frame can be modified arbitrarily. Supports TCP, ICMP and UDP data as well, with input from either keyboard as UTF-8/ASCII, keyboard as hexadecimal, or from file. Various other features exist as well.
