TestSSL 2.9.5-4
Posted Apr 9, 2018
Authored by Dr. Dirk Wetter | Site drwetter.org

testssl.sh is a free command line tool which checks a server's service on any port for the support of TLS/SSL ciphers, protocols as well as recent cryptographic flaws, and much more. It is written in (pure) bash, makes only use of standard Unix utilities, openssl and last but not least bash sockets.

Changes: This update contains a bugfix (and a clarification in help/documentation) only. It does not contain any new features.

Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2018-0646-01 - The python-paramiko package provides a Python module that implements the SSH2 protocol for encrypted and authenticated connections to remote machines. Unlike SSL, the SSH2 protocol does not require hierarchical certificates signed by a powerful central authority. The protocol also includes the ability to open arbitrary channels to remote services across an encrypted tunnel. Issues addressed include a bypass vulnerability.

Wireshark Analyzer 2.4.6
Posted Apr 3, 2018
Authored by Gerald Combs | Site wireshark.org

Wireshark is a GTK+-based network protocol analyzer that lets you capture and interactively browse the contents of network frames. The goal of the project is to create a commercial-quality analyzer for Unix and Win32 and to give Wireshark features that are missing from closed-source sniffers.

Changes: Many vulnerabilities have been fixed.

Debian Security Advisory 4154-1
Posted Mar 28, 2018
Authored by Debian | Site debian.org

Debian Linux Security Advisory 4154-1 - A heap corruption vulnerability was discovered in net-snmp, a suite of Simple Network Management Protocol applications, triggered when parsing the PDU prior to the authentication process. A remote, unauthenticated attacker can take advantage of this flaw to crash the snmpd process (causing a denial of service) or, potentially, execute arbitrary code with the privileges of the user running snmpd.

Nmap Port Scanner 7.70
Posted Mar 21, 2018
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: Integrated 728 service/version detection fingerprints. Integrated 667 IPv4 OS fingerprint submissions. Integrated 33 IPv6 OS fingerprint submissions. Added 9 NSE scripts. Various other updates and fixes.
