FreeBSD Security Advisory FreeBSD-SA-09:04.bind
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ============================================================================FreeBSD-SA-09:04.bind Security Advisory The FreeBSD Project Topic: BIND DNSSEC incorrect checks for malformed signatures Category: contrib Module: bind Announced: 2009-01-13 Credits: Google Security Team Affects: All supported FreeBSD versions Corrected: 2009-01-10 03:00:21 UTC (RELENG_7, 7.1-STABLE) 2009-01-13 21:19:27 UTC (RELENG_7_1, 7.1-RELEASE-p2) 2009-01-13 21:19:27 UTC (RELENG_7_0, 7.0-RELEASE-p9) 2009-01-10 04:30:27 UTC (RELENG_6, 6.4-STABLE) 2009-01-13 21:19:27 UTC (RELENG_6_4, 6.4-RELEASE-p3) 2009-01-13 21:19:27 UTC (RELENG_6_3, 6.3-RELEASE-p9) CVE Name: CVE-2009-0025 For general information regarding FreeBSD Security Advisories, including descriptions of the fields above, security branches, and the following sections, please visit <URL:http://security.FreeBSD.org/>. I. Background BIND 9 is an implementation of the Domain Name System (DNS) protocols. The named(8) daemon is an Internet Domain Name Server. DNS Security Extensions (DNSSEC) are additional protocol options that add authentication as part of responses to DNS queries. FreeBSD includes software from the OpenSSL Project. The OpenSSL Project is a collaborative effort to develop a robust, commercial-grade, full-featured Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as a full-strength general purpose cryptography library. II. Problem Description The DSA_do_verify() function from OpenSSL is used to determine if a DSA digital signature is valid. When DNSSEC is used within BIND it uses DSA_do_verify() to verify DSA signatures, but checks the function return value incorrectly. III. Impact It is in theory possible to spoof a DNS reply even though DNSSEC is set up to validate answers. This could be used by an attacker for man-in-the-middle or other spoofing attacks. IV. Workaround Disable the the DSA algorithm in named.conf. This will cause answers from zones signed only with DSA to be treated as insecure. Add the following to the options section of named.conf: disable-algorithms . { DSA; }; NOTE WELL: If named(8) is not explicitly set to use DNSSEC the setup is not vulnerable to the issue as described in this Security Advisory. V. Solution Perform one of the following: 1) Upgrade your vulnerable system to 6-STABLE, or 7-STABLE, or to the RELENG_7_1, RELENG_7_0, RELENG_6_4, or RELENG_6_3 security branch dated after the correction date. 2) To patch your present system: The following patches have been verified to apply to FreeBSD 6.3, 6.4, 7.0, and 7.1 systems. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility. # fetch http://security.FreeBSD.org/patches/SA-09:04/bind.patch # fetch http://security.FreeBSD.org/patches/SA-09:04/bind.patch.asc b) Execute the following commands as root: # cd /usr/src # patch < /path/to/patch # cd /usr/src/lib/bind # make obj && make depend && make && make install # cd /usr/src/usr.sbin/named # make obj && make depend && make && make install # /etc/rc.d/named restart c) Install and use a fixed version of BIND from the FreeBSD Ports Collection. VI. Correction details The following list contains the revision numbers of each file that was corrected in FreeBSD.

FreeBSD Security Advisory FreeBSD-SA-09:04.bind
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ============================================================================FreeBSD-SA-09:04.bind Security Advisory The FreeBSD Project Topic: BIND DNSSEC incorrect checks for malformed signatures Category: contrib Module: bind Announced: 2009-01-13 Credits: Google Security Team Affects: All supported FreeBSD versions Corrected: 2009-01-10 03:00:21 UTC (RELENG_7, 7.1-STABLE) 2009-01-13 21:19:27 UTC (RELENG_7_1, 7.1-RELEASE-p2) 2009-01-13 21:19:27 UTC (RELENG_7_0, 7.0-RELEASE-p9) 2009-01-10 04:30:27 UTC (RELENG_6, 6.4-STABLE) 2009-01-13 21:19:27 UTC (RELENG_6_4, 6.4-RELEASE-p3) 2009-01-13 21:19:27 UTC (RELENG_6_3, 6.3-RELEASE-p9) CVE Name: CVE-2009-0025 For general information regarding FreeBSD Security Advisories, including descriptions of the fields above, security branches, and the following sections, please visit <URL:http://security.FreeBSD.org/>. I. Background BIND 9 is an implementation of the Domain Name System (DNS) protocols. The named(8) daemon is an Internet Domain Name Server. DNS Security Extensions (DNSSEC) are additional protocol options that add authentication as part of responses to DNS queries. FreeBSD includes software from the OpenSSL Project. The OpenSSL Project is a collaborative effort to develop a robust, commercial-grade, full-featured Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as a full-strength general purpose cryptography library. II. Problem Description The DSA_do_verify() function from OpenSSL is used to determine if a DSA digital signature is valid. When DNSSEC is used within BIND it uses DSA_do_verify() to verify DSA signatures, but checks the function return value incorrectly. III. Impact It is in theory possible to spoof a DNS reply even though DNSSEC is set up to validate answers. This could be used by an attacker for man-in-the-middle or other spoofing attacks. IV. Workaround Disable the the DSA algorithm in named.conf. This will cause answers from zones signed only with DSA to be treated as insecure. Add the following to the options section of named.conf: disable-algorithms . { DSA; }; NOTE WELL: If named(8) is not explicitly set to use DNSSEC the setup is not vulnerable to the issue as described in this Security Advisory. V. Solution Perform one of the following: 1) Upgrade your vulnerable system to 6-STABLE, or 7-STABLE, or to the RELENG_7_1, RELENG_7_0, RELENG_6_4, or RELENG_6_3 security branch dated after the correction date. 2) To patch your present system: The following patches have been verified to apply to FreeBSD 6.3, 6.4, 7.0, and 7.1 systems. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility. # fetch http://security.FreeBSD.org/patches/SA-09:04/bind.patch # fetch http://security.FreeBSD.org/patches/SA-09:04/bind.patch.asc b) Execute the following commands as root: # cd /usr/src # patch < /path/to/patch # cd /usr/src/lib/bind # make obj && make depend && make && make install # cd /usr/src/usr.sbin/named # make obj && make depend && make && make install # /etc/rc.d/named restart c) Install and use a fixed version of BIND from the FreeBSD Ports Collection. VI. Correction details The following list contains the revision numbers of each file that was corrected in FreeBSD.
