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.

42e2b3796ac07fc1dbafc7abcc002cd3Netzob supports the expert in reverse engineering, evaluation, and simulation of communication protocols. Its main goals are to help security evaluators to assess the robustness of proprietary or unknown protocol implementations, simulate realistic communications to test third-party products (IDS, firewalls, etc.), and create an Open Source implementation of a proprietary or unknown protocol. Netzob provides a semi-automatic inferring process, and includes everything necessary to passively learn the vocabulary of a protocol and actively infer its grammar. The learnt protocol can afterward be simulated. Netzob handles text protocols (like HTTP and IRC), fixed field protocols (like IP and TCP), and variable field protocols (like ASN.1-based formats).
2d129a4680a6d492938635abf7500eeastrongSwan is a complete IPsec implementation for the Linux, Android, Maemo, FreeBSD, and Mac OS X operating systems. It interoperates with with most other IPsec-based VPN products via the IKEv2 or IKEv1 key exchange protocols. The focus of the strongSwan project is on strong authentication mechanisms using X.509 public key certificates and optional secure storage of private keys on smartcards through a standardized PKCS#11 interface. A rich choice of modular plugins adds additional features like Trusted Network Connect or advanced cryptographical algorithms.
2a1b0bca846a966a56f662f855ced9fbRed Hat Security Advisory 2012-0533-01 - Samba is an open-source implementation of the Server Message Block or Common Internet File System protocol, which allows PC-compatible machines to share files, printers, and other information. A flaw was found in the way Samba handled certain Local Security Authority Remote Procedure Calls. An authenticated user could use this flaw to issue an RPC call that would modify the privileges database on the Samba server, allowing them to steal the ownership of files and directories that are being shared by the Samba server, and create, delete, and modify user accounts, as well as other Samba server administration tasks.

c4a7ca65d102d5fbddb0b26479033d43Cisco Security Advisory - The Cisco IOS Software Network Address Translation (NAT) feature contains a denial of service (DoS) vulnerability in the translation of Session Initiation Protocol (SIP) packets. The vulnerability is caused when packets in transit on the vulnerable device require translation on the SIP payload. Cisco has released free software updates that address this vulnerability. A workaround that mitigates the vulnerability is available.
920c60096f97c3c32d7c7e718116a777netsniff-ng is is a free, performant Linux network sniffer for packet inspection. The gain of performance is reached by 'zero-copy' mechanisms, so that the kernel does not need to copy packets from kernelspace to userspace. For this purpose netsniff-ng is libpcap independent, but nevertheless supports the pcap file format for capturing, replaying and performing offline-analysis of pcap dumps. netsniff-ng can be used for protocol analysis, reverse engineering and network debugging.

This vulnerability could allow an unauthenticated, remote attacker to cause an interface wedge, which can lead to loss of connectivity, loss of routing protocol adjacency, and other denial of service (DoS) conditions. This vulnerability could be exploited repeatedly to cause an extended DoS condition. A workaround is available to mitigate this vulnerability. Cisco has released free software updates that address this vulnerability.

b5735a05ea328e59463680284c941794Red Hat Security Advisory 2012-0429-01 - The GnuTLS library provides support for cryptographic algorithms and for protocols such as Transport Layer Security. A flaw was found in the way GnuTLS decrypted malformed TLS records. This could cause a TLS/SSL client or server to crash when processing a specially-crafted TLS record from a remote TLS/SSL connection peer. A boundary error was found in the gnutls_session_get_data() function. A malicious TLS/SSL server could use this flaw to crash a TLS/SSL client or, possibly, execute arbitrary code as the client, if the client passed a fixed-sized buffer to gnutls_session_get_data() before checking the real size of the session data provided by the server.
54b74ddd5981eec1a2ef266668b9f83fRed Hat Security Advisory 2012-0426-01 - OpenSSL is a toolkit that implements the Secure Sockets Layer and Transport Layer Security protocols, as well as a full-strength, general purpose cryptography library. A NULL pointer dereference flaw was found in the way OpenSSL parsed Secure/Multipurpose Internet Mail Extensions messages. An attacker could use this flaw to crash an application that uses OpenSSL to decrypt or verify S/MIME messages. A flaw was found in the PKCS#7 and Cryptographic Message Syntax implementations in OpenSSL. An attacker could possibly use this flaw to perform a Bleichenbacher attack to decrypt an encrypted CMS, PKCS#7, or S/MIME message by sending a large number of chosen ciphertext messages to a service using OpenSSL and measuring error response times.
