NAMED_V592P010 - NAMED ECO kit Rev 1.0 for TCPware 5.9-2 3-Mar-2010 Copyright © 2010 Process Software, LLC This kit updates TCPware versions 5.9-2 and 5.8-2 with version 9.6.1-p3 of the Bind 9 Nameserver (NAMED.EXE), RNDC, and NSUPDATE images. NOTE : Due to the size of the Nameserver component, the supporting tools (including DIG.EXE, DNSSEC-KEYGEN.EXE, DNSSEC-SIGNZONE.EXE, HOST.EXE, NAMED-CHECKCONF.EXE, NAMED-CHECKZONE.EXE, and NSLOOKUP.EXE) can be found in the ECO NAMED-TOOLS_V582P010 or later. The two ECOs are independent of each other and can be installed at any time. The ranking for this ECO is 1. The overall ranking for it is 0. NAMED_V592P010 -- ECO Rank 1 -------------------------------------------------------------------------- The following changes have been made in this kit: - Corrects problem when using RNDC from a remote host to control a TCPware NAMED server. (D/E 10983) - Incorporated BIND 9.6.1-P3 updates, which is a SECURITY PATCH for BIND 9.6.1. It addresses two potential cache poisoning vulnerabilities, both of which could allow a validating recursive nameserver to cache data which had not been authenticated or was invalid. (D/E 10981) - Addresses performance issues for NAMED server on VAX (D/E 10946) - When validating with DNSSEC, track whether pending data was from the additional section or not and only return it if it validates as secure (CVE-2009-4022). (D/E 10945) - Added support for SPF and IPSEC RR data types (D/E 10931) This kit also includes the following changes from previous ECOs : - Implemented ISC security fix to protect against DoS attacks with dynamic updates (ISC BIND 9.6.1-p1) (ECO NAMED_V582P020 D/E 10893) - Upgraded to version 9.6.1 of the Bind 9 codebase, the most recent ISC release. (ECO NAMED_V582P020 D/E 10883) Bind 9.6.1 has a number of new features over previous versions, including, but not limited to: - Full NSEC3 support - Automatic zone re-signing - New update-policy methods tcp-self and 6to4-self - Improved statistics reporting - Added functionality to specify a specific operator class for OPCOM messages. Using the logical TCPWARE_NAMED_OPCOM_TARGET a system administrator can define a value from OPER1 through OPER12. For example, to direct the opcoms to OPER8, use the command : $ DEFINE/SYSTEM/EXEC TCPWARE_NAMED_OPCOM_TARGET "OPER8" To then see the opcom messages : $ REPLY/ENABLE=OPER8 The default or undefined value is the NETWORK class. (ECO NAMED_V582P020 D/E 10409) - Implement latest ISC security patch. ISC released 9.4.2-p1 to combat a potential attack exploiting weaknesses in the DNS protocol which can enable the poisoning of caching recursive resolvers with spoofed data. (ECO NAMED_V582P010 D/E 10750) -------------------------------------------------------------------------- For further information on using RNDC and other BIND tools, we recommend referring to the latest edition of O'Reilly's DNS and BIND. To run any of the support tools, define symbols, i.e.: $ nsupdate :== $tcpware:nsupdate.exe $ rndc :== $tcpware:rndc.exe $ rndcconfgen :== $tcpware:rndc-confgen.exe You need to restart the Nameserver for these changes to take effect. The following command will do it: $ @tcpware:restart dns
