Nmap Port Scanner 7.93
Posted Sep 2, 2022
Authored by Fyodor | Site insecure.org

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.

Changes: This release commemorates Nmap's 25th anniversary! 20 updates are included. For Ncat, they fixed hostname/certificate comparison and matching to handle ASN.1 strings without null terminators, a similar bug to OpenSSL's CVE-2021-3712 and also added support for SOCKS5 proxies that return bind addresses as hostnames, instead of IPv4/IPv6 addresses.

Red Hat Security Advisory 2022-6113-01 - Red Hat Application Interconnect 1.0 introduces a service network, linking TCP and HTTP services across the hybrid cloud. A service network enables communication between services running in different network locations or sites. It allows geographically distributed services to connect as if they were all running in the same site. This is an update to the rpms for Red Hat Application Interconnect 1.0 to fix some security issues in the golang compiler.

GNUnet P2P Framework 0.17.4
Posted Aug 12, 2022
Authored by Christian Grothoff | Site ovmj.org

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.

Changes: This is a bugfix release for gnunet 0.17.3 because of a missing file in the tarball required to build the documentation.
