Wireshark Analyzer 2.2.8
Posted Jul 19, 2017
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: Updated manuf, services enterprise numbers, translations, and other items. Various other updates.

Red Hat Security Advisory 2017-1721-01
Posted Jul 12, 2017
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2017-1721-01 - The httpd packages provide the Apache HTTP Server, a powerful, efficient, and extensible web server. Security Fix: It was discovered that the HTTP parser in httpd incorrectly allowed certain characters not permitted by the HTTP protocol specification to appear unencoded in HTTP request headers. If httpd was used in conjunction with a proxy or backend server that interpreted those characters differently, a remote attacker could possibly use this flaw to inject data into HTTP responses, resulting in proxy cache poisoning.

Red Hat Security Advisory 2017-1680-01 - The Berkeley Internet Name Domain is an implementation of the Domain Name System protocols. BIND includes a DNS server ; a resolver library ; and tools for verifying that the DNS server is operating correctly. Security Fix: A flaw was found in the way BIND handled TSIG authentication for dynamic updates. A remote attacker able to communicate with an authoritative BIND server could use this flaw to manipulate the contents of a zone, by forging a valid TSIG or SIG signature for a dynamic update request.

GNU Transport Layer Security Library 3.3.28
Posted Jul 4, 2017
Authored by Simon Josefsson, Nikos Mavrogiannopoulos | Site gnu.org

GnuTLS is a secure communications library implementing the SSL and TLS protocols and technologies around them. It provides a simple C language application programming interface (API) to access the secure communications protocols, as well as APIs to parse and write X.509, PKCS #12, OpenPGP, and other required structures. It is intended to be portable and efficient with a focus on security and interoperability.

Changes: Various updates.

Red Hat Security Advisory 2017-1583-01 - The Berkeley Internet Name Domain is an implementation of the Domain Name System protocols. BIND includes a DNS server ; a resolver library ; and tools for verifying that the DNS server is operating correctly. Security Fix: A denial of service flaw was found in the way BIND handled responses containing a DNAME answer. A remote attacker could use this flaw to make named exit unexpectedly with an assertion failure via a specially crafted DNS response.

Nmap Port Scanner 7.50
Posted Jun 14, 2017
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 all of the service/version detection fingerprints submitted from September to March (855 of them). The signature count went up 2.9% to 11,418. It now detects 1193 protocols from apachemq, bro, and clickhouse to jmon, slmp, and zookeeper. Added 14 NSE scripts from 12 authors, bringing the total up to 566! Various other updates.

Security Fix: It was found that Samba always requested forwardable tickets when using Kerberos authentication. A service to which Samba authenticated using Kerberos could subsequently use the ticket to impersonate Samba to other services or domain users.

Red Hat Security Advisory 2017-1209-01 - The rhev-hypervisor package provides a Red Hat Enterprise Virtualization Hypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine hypervisor. It includes everything necessary to run and manage virtual machines: A subset of the Red Hat Enterprise Linux operating environment and the Red Hat Enterprise Virtualization Agent. Security Fix: A use-after-free flaw was found in the way the Linux kernel's Datagram Congestion Control Protocol implementation freed SKB resources for a DCCP_PKT_REQUEST packet when the IPV6_RECVPKTINFO option is set on the socket. A local, unprivileged user could use this flaw to alter the kernel memory, allowing them to escalate their privileges on the system.
