-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Announcement Package: curl, wget Announcement ID: SUSE-SA:2005:063 Date: Mon, 24 Oct 2005 16:00:00 +0000 Affected Products: SUSE LINUX 10.0 SUSE LINUX 9.3 SUSE LINUX 9.2 SUSE LINUX 9.1 SUSE Linux Enterprise Server 9 Novell Linux Desktop 9 Open Enterprise Server Vulnerability Type: remote code execution Severity (1-10): 7 SUSE Default Package: yes Cross-References: CVE-2005-3185 Content of This Advisory: 1) Security Vulnerability Resolved: stack based buffer overflow in NTLM authentication 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 This update fixes a stack-based buffer overflow in the NTLM authentication code used by the file download tools/libraries curl and wget that can be triggered by using a long user or domain name (also works with HTTP redirects). By exploiting this bug by using a malicious server an attacker may be able to execute arbitrary code with the privileges of the entity running the process locally. (CVE-2005-3185) This affects both curl/libcurl and wget >= 1.10. wget copied the code from libcurl, making this effectively the same 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 programs using libcurl 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/compat-curl2-7.11.0-7.2.i586.rpm 8f5ea41e7b4e80798c960790bb93e603 ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/i586/curl-7.14.0-2.2.i586.rpm 8e59e94e8745f0916ed00a7040d4e597 ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/i586/wget-1.10.1-2.2.i586.rpm 2a91b99e5adfd78b2e9c6a3b03bcc67d SUSE LINUX 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/compat-curl2-7.11.0-6.2.i586.rpm dc1b2e8dc509adca503b7f2e7724be49 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/curl-7.13.0-5.2.i586.rpm 937855b131da29025f48cab5880a91ea ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/wget-1.10-1.3.i586.rpm 556ba3000c278fecfec9c24b1b5ce44f SUSE LINUX 9.2: ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/i586/compat-curl2-7.11.0-4.4.i586.rpm 2b21dc3b9877f45602191cc33c695734 ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/i586/curl-7.12.0-2.4.i586.rpm 77802b5fb55775fd00b1e7e71cb03aab SUSE LINUX 9.1: ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/i586/curl-7.11.0-39.9.i586.rpm 8f18c55e56f560e641173b7ca96a13a6 ftp://ftp.suse.com/pub/suse/x86_64/update/9.1/rpm/i586/curl-32bit-9.1-200510171252.i586.rpm 07b00ace15bc16b4e6ee878cb4703f34 Power PC Platform: SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/ppc/compat-curl2-7.11.0-7.2.ppc.rpm b69c93ed024d1887cb1fafa9140c7235 ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/ppc/curl-7.14.0-2.2.ppc.rpm 1102f6dd51867fb06921e1b35354821d ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/ppc/wget-1.10.1-2.2.ppc.rpm ba717462ca2644628296cb473f228926 x86-64 Platform: SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/compat-curl2-32bit-7.11.0-7.2.x86_64.rpm e42d1a8642003893cc2656effc2befae ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/compat-curl2-7.11.0-7.2.x86_64.rpm f29e8a213abc2a6df3c514849dd58f45 ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/curl-32bit-7.14.0-2.2.x86_64.rpm 531e4e3a333cd7a869bce42d4f284c34 ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/curl-7.14.0-2.2.x86_64.rpm d11fd9298ca5a0d6009810afc02ffa00 ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/wget-1.10.1-2.2.x86_64.rpm 4025598d1a4d5c1f3bfb288df9ba62e0 SUSE LINUX 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/x86_64/compat-curl2-32bit-9.3-7.1.x86_64.rpm 8064b387585923ca8bf897294d6e0750 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/x86_64/compat-curl2-7.11.0-6.2.x86_64.rpm c6174cc85a1a8a7ae0aef33703b255ab ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/x86_64/curl-32bit-9.3-7.1.x86_64.rpm d4da6969e3c7c08c2387bf2f491ae6b2 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/x86_64/curl-7.13.0-5.2.x86_64.rpm d6db8fa9847c74194db4b11508aa81e5 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/x86_64/wget-1.10-1.3.x86_64.rpm 62373d0f58db04c85d6d558002b61439 SUSE LINUX 9.2: ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/x86_64/compat-curl2-32bit-9.2-200510171251.x86_64.rpm 8176f04bcc6b8a5b5e6730570d71e1dc ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/x86_64/compat-curl2-7.11.0-4.4.x86_64.rpm 77ca0f684608cd05d6680b71a60f3d2b ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/x86_64/curl-7.12.0-2.4.x86_64.rpm 225eaed129a89f522099a4dd05fbd92f SUSE LINUX 9.1: ftp://ftp.suse.com/pub/suse/x86_64/update/9.1/rpm/x86_64/curl-7.11.0-39.9.x86_64.rpm c7e53c0f5b9e176ea517b2cd6e212b7b Sources: SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/src/compat-curl2-7.11.0-7.2.src.rpm dd327d44a1e34dc62557d731191d8eaa ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/src/curl-7.14.0-2.2.src.rpm 501302472341f049f32c26158857afe4 ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/src/wget-1.10.1-2.2.src.rpm 620602e6c0d6745278570b049dc62d6f SUSE LINUX 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/src/compat-curl2-7.11.0-6.2.src.rpm f28644961a98a391fcd4f9c220d95976 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/src/curl-7.13.0-5.2.src.rpm 115bbe666fc6d170f0209bf08d415e94 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/src/wget-1.10-1.3.src.rpm 201a3d45868f65590bb78bb80f40c1f5 SUSE LINUX 9.2: ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/src/compat-curl2-7.11.0-4.4.src.rpm 9c3f454a7d31bddee04df39a6b10052c ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/src/curl-7.12.0-2.4.src.rpm f5249c9853905e77323c6febfe319809 SUSE LINUX 9.1: ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/src/curl-7.11.0-39.9.src.rpm c64049955adb7067312b8716e61e2819 ftp://ftp.suse.com/pub/suse/x86_64/update/9.1/rpm/src/curl-7.11.0-39.9.src.rpm 9bb9bd0870ab5a6a76e5da583323ca98 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. All SUSE security announcements are sent to this list. To subscribe, send an e-mail to <suse-security-subscribe@suse.com>. suse-security-announce@suse.com - SUSE's announce-only mailing list. Only SUSE's security announcements are sent to this list. To subscribe, send an e-mail to <suse-security-announce-subscribe@suse.com>.
