-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Announcement Package: ipsec-tools,freeswan,openswan Announcement ID: SUSE-SA:2005:070 Date: Tue, 20 Dec 2005 11:00:00 +0000 Affected Products: SUSE LINUX 10.0 SUSE LINUX 9.3 SUSE LINUX 9.2 SUSE LINUX 9.1 SUSE Linux Enterprise Server 9 Vulnerability Type: remote denial of service Severity (1-10): 5 SUSE Default Package: no Cross-References: CVE-2005-3671, CVE-2005-3732 Content of This Advisory: 1) Security Vulnerability Resolved: Internet Key Exchange v1 problems in various IPsec implementations Problem Description 2) Solution or Work-Around 3) Special Instructions and Notes 4) Package Location and Checksums 5) Pending Vulnerabilities, Solutions, and Work-Arounds: See SUSE Security Summary Report. 6) Authenticity Verification and Additional Information ______________________________________________________________________________ 1) Problem Description and Brief Discussion Openswan, Freeswan and raccoon (ipsec-tools) have been updated to fix crashes in aggressive mode. An attacker might send specially crafted packets that can crash racoon or Pluto. The ipsec-tools / racoon crashes are tracked by the Mitre CVE ID CVE-2005-3732. The openswan / freeswan crashes are tracked by the Mitre CVE ID CVE-2005-3671. SUSE Linux Enterprise Server 8 and SUSE Linux 9.0 contain freeswan 1.x and seem no to be affected by this problem. 2) Solution or Work-Around There is no known workaround, please install the update packages. 3) Special Instructions and Notes Please close and restart all running instances of openswan, freeswan or racoon after the update. 4) Package Location and Checksums The preferred method for installing security updates is to use the YaST Online Update (YOU) tool. YOU detects which updates are required and automatically performs the necessary steps to verify and install them. Alternatively, download the update packages for your distribution manually and verify their integrity by the methods listed in Section 6 of this announcement. Then install the packages using the command rpm -Fhv <file.rpm> to apply the update, replacing <file.rpm> with the filename of the downloaded RPM package. x86 Platform: SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/i586/ipsec-tools-0.6-4.2.i586.rpm f82b5941ca8143a7f81315f2309c28e9 ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/i586/openswan-2.4.4-1.1.i586.rpm 9d2318b4da837ae3175547ba261235c5 SUSE LINUX 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/ipsec-tools-0.5-5.2.i586.rpm 57b586b7aaa612c6250a8b037afe9335 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/openswan-2.2.0-12.4.i586.rpm 6c152ba37641677fc4c59c44199a9225 SUSE LINUX 9.2: ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/i586/ipsec-tools-0.4rc1-3.4.i586.rpm ca1ffa39b311744976bc9754f003c71f ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/i586/openswan-2.2.0-8.4.i586.rpm 88dedfd8ad12456158b0f60d0a4714f4 SUSE LINUX 9.1: ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/i586/freeswan-2.04_1.5.4-1.23.i586.rpm 64b2fc324586f4af0060b8dd0c6597eb ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/i586/ipsec-tools-0.3.3-1.9.i586.rpm c523ed28073d5d76a1468763cc3820ea Power PC Platform: SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/ppc/ipsec-tools-0.6-4.2.ppc.rpm fc12c770db47d6a51b7cfc7e92b0f003 ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/ppc/openswan-2.4.4-1.1.ppc.rpm 6a0c80ce5f3a489221e605ea7ee724d5 x86-64 Platform: SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/ipsec-tools-0.6-4.2.x86_64.rpm 7550e022c5557841a06c6334d1a2632c ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/openswan-2.4.4-1.1.x86_64.rpm b25da775ec60a014febb111179a42e91 SUSE LINUX 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/x86_64/ipsec-tools-0.5-5.2.x86_64.rpm 8ee673f4f3386e6e0a5ea123cad19064 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/x86_64/openswan-2.2.0-12.4.x86_64.rpm b65ee8de2eae744f40b7d33ae912995c SUSE LINUX 9.2: ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/x86_64/ipsec-tools-0.4rc1-3.4.x86_64.rpm 8e4f8794e3f8322b4b5c301d964cfabd ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/x86_64/openswan-2.2.0-8.4.x86_64.rpm 30af3b8e87fe2018ae2b4a1a884887e2 SUSE LINUX 9.1: ftp://ftp.suse.com/pub/suse/x86_64/update/9.1/rpm/x86_64/freeswan-2.04_1.5.4-1.23.x86_64.rpm dbdf3e6c1d45a0e42f0facfd78edc29c ftp://ftp.suse.com/pub/suse/x86_64/update/9.1/rpm/x86_64/ipsec-tools-0.3.3-1.9.x86_64.rpm bcf17a5cd915276de386e8181c87ec99 Sources: SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/src/ipsec-tools-0.6-4.2.src.rpm 6ecfb0963c478d0962fad9146110466c ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/src/openswan-2.4.4-1.1.src.rpm e8f841c893e062f2e378eb269ba7d128 SUSE LINUX 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/src/ipsec-tools-0.5-5.2.src.rpm 0944add00587f50f20c5f7a38fac5b4f ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/src/openswan-2.2.0-12.4.src.rpm 5d89968ca8f4b1718f0018c8c466ddf9 SUSE LINUX 9.2: ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/src/ipsec-tools-0.4rc1-3.4.src.rpm 26d12b6a99b2723272a74f402ba4ff58 ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/src/openswan-2.2.0-8.4.src.rpm f097a1113a838a007c586c72bb7e43a2 SUSE LINUX 9.1: ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/src/freeswan-2.04_1.5.4-1.23.src.rpm 362067f9c39a902c433af5f998b4eecf ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/src/ipsec-tools-0.3.3-1.9.src.rpm b7443b44f2ee6cab65f214e6e983f113 ftp://ftp.suse.com/pub/suse/x86_64/update/9.1/rpm/src/freeswan-2.04_1.5.4-1.23.src.rpm 95d18a7cf39acaabb747edfc7b5411cd ftp://ftp.suse.com/pub/suse/x86_64/update/9.1/rpm/src/ipsec-tools-0.3.3-1.9.src.rpm 517f4afbe1f3d1b3ad554582d4463bb2 Our maintenance customers are notified individually.

The authenticity and integrity of a SUSE security announcement is guaranteed by a cryptographic signature in each announcement. All SUSE security announcements are published with a valid signature. To verify the signature of the announcement, save it as text into a file and run the command gpg --verify <file> replacing <file> with the name of the file where you saved the announcement. The output for a valid signature looks like: gpg: Signature made <DATE> using RSA key ID 3D25D3D9 gpg: Good signature from "SuSE Security Team <security@suse.de>" where <DATE> is replaced by the date the document was signed. If the security team's key is not contained in your key ring, you can import it from the first installation CD. To import the key, use the command gpg --import gpg-pubkey-3d25d3d9-36e12d04.asc - Package authenticity verification: SUSE update packages are available on many mirror FTP servers all over the world. While this service is considered valuable and important to the free and open source software community, the authenticity and the integrity of a package needs to be verified to ensure that it has not been tampered with. There are two verification methods that can be used independently from each other to prove the authenticity of a downloaded file or RPM package: 1) Using the internal gpg signatures of the rpm package 2) MD5 checksums as provided in this announcement 1) The internal rpm package signatures provide an easy way to verify the authenticity of an RPM package. Use the command rpm -v --checksig <file.rpm> to verify the signature of the package, replacing <file.rpm> with the filename of the RPM package downloaded. The package is unmodified if it contains a valid signature from build@suse.de with the key ID 9C800ACA. This key is automatically imported into the RPM database (on RPMv4-based distributions) and the gpg key ring of 'root' during installation. You can also find it on the first installation CD and at the end of this announcement. 2) If you need an alternative means of verification, use the md5sum command to verify the authenticity of the packages. Execute the command md5sum <filename.rpm> after you downloaded the file from a SUSE FTP server or its mirrors. Then compare the resulting md5sum with the one that is listed in the SUSE security announcement. Because the announcement containing the checksums is cryptographically signed (by security@suse.de), the checksums show proof of the authenticity of the package if the signature of the announcement is valid. Note that the md5 sums published in the SUSE Security Announcements are valid for the respective packages only. Newer versions of these packages cannot be verified. - SUSE runs two security mailing lists to which any interested party may subscribe: suse-security@suse.com - General Linux and SUSE security discussion.
