Mandriva Linux Security Advisory 2013-167 - OpenVPN 2.3.0 and earlier running in UDP mode are subject to chosen ciphertext injection due to a non-constant-time HMAC comparison function. Plaintext recovery may be possible using a padding oracle attack on the CBC mode cipher implementation of the crypto library, optimistically at a rate of about one character per 3 hours. PolarSSL seems vulnerable to such an attack; the vulnerability of OpenSSL has not been verified or tested.

Mandriva Linux Security Advisory 2013-072 - When dnsmasq before 2.63 is used in conjunctions with certain configurations of libvirtd, network packets from prohibited networks may be sent to the dnsmasq application and processed. This can result in DNS amplification attacks for example. This update adds a new option --bind-dynamic which is immune to this problem. This update completes the fix for provided with dnsmasq-2.63. It was found that after the upstream patch for - replied to remote TCP-protocol based DNS queries (UDP protocol ones were corrected, but TCP ones not) from prohibited networks, when the --bind-dynamic option was used, - when --except-interface lo option was used dnsmasq didn't answer local or remote UDP DNS queries, but still allowed TCP protocol based DNS queries, - when --except-interface lo option was not used local / remote TCP DNS queries were also still answered by dnsmasq. This update fix these three cases.

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.

Asterisk Project Security Advisory - Asterisk has several places where messages received over various network transports may be copied in a single stack allocation. In the case of TCP, since multiple packets in a stream may be concatenated together, this can lead to large allocations that overflow the stack. In the case of SIP, it is possible to do this before a session is established. Keep in mind that SIP over UDP is not affected by this vulnerability. With HTTP and XMPP, a session must first be established before the vulnerability may be exploited. The XMPP vulnerability exists both in the res_jabber.so module in Asterisk 1.8, 10, and 11 as well as the res_xmpp.so module in Asterisk 11.

Siemens SIMATIC S7-1200 PLCs, version 2 and higher, allow device management over TCP port 102 (ISO-TSAP) and retrieving status information over UDP port 161 (SNMP). It is possible to cause the device to go into defect mode by sending specially crafted packets to these ports.

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.

This Metasploit module exploits a remote buffer overflow in HP Intelligent Management Center UAM. The vulnerability exists in the uam.exe component, when using sprint in a insecure way for logging purposes. The vulnerability can be triggered by sending a malformed packet to the 1811/UDP port. The module has been successfully tested on HP iMC 5.0 E0101 and UAM 5.0 E0102 over Windows Server 2003 SP2 (DEP bypass).

Zero Day Initiative Advisory 12-171 - This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Hewlett-Packard Intelligent Management Center. Authentication is not required to exploit this vulnerability. The flaw exists within the uam.exe component which listens by default on UDP port 1811. When logging received actions to a log file, sprintf is used to build the log message. The process does not properly verify the destination buffer on the stack is of sufficient size to handle the newly created string. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of the SYSTEM user.

Secunia Research has discovered two vulnerabilities in Network Instruments Observer, which can be exploited by malicious people to compromise a vulnerable system. A boundary error in the "CSnmp::DecodePacket()" method (NISNMP.DLL) when processing the community string can be exploited to cause a heap-based buffer overflow via a specially crafted SNMP datagram. An error in the "CSnmp::DecodePacket()" method (NISNMP.DLL) when processing an Object Identifier (OID) can be exploited to cause a heap-based buffer overflow via a specially crafted Trap PDU (0xA4) SNMP datagram sent to UDP port 162. Successful exploitation of the vulnerabilities allows execution of arbitrary code, but may require the attacker to enumerate or guess the SNMP port. Observer version 15.1 Build 0007.0000 is affected.

Debian Linux Security Advisory 2442-1 - It has been discovered that spoofed "getstatus" UDP requests are being sent by attackers to servers for use with games derived from the Quake 3 engine (such as openarena). These servers respond with a packet flood to the victim whose IP address was impersonated by the attackers, causing a denial of service.
