-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Announcement Package: opera Announcement ID: SUSE-SA:2005:057 Date: Mon, 26 Sep 2005 15:00:00 +0000 Affected Products: SUSE LINUX 10.0 SUSE LINUX OSS 10.0 SUSE LINUX 9.3 SUSE LINUX 9.2 SUSE LINUX 9.1 SuSE Linux 9.0 Vulnerability Type: remote code execution Severity (1-10): 6 SUSE Default Package: yes Cross-References: CAN-2005-3006 CAN-2005-3007 Content of This Advisory: 1) Security Vulnerability Resolved: opera script insertion problems 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 upgrades the Opera web browser to the 8.50 release. Besides the changes in 8.50 that are listed in http://www.opera.com/docs/changelogs/linux/850/ following security problems were fixed: 1. Attached files are opened without any warnings directly from the user's cache directory. This can be exploited to execute arbitrary Javascript in context of "file://". 2. Normally, filename extensions are determined by the "Content-Type" in Opera Mail. However, by appending an additional '.' to the end of a filename, an HTML file could be spoofed to be e.g. "image.jpg.". These two vulnerabilities combined may be exploited to conduct script insertion attacks if the user chooses to view an attachment named e.g. "image.jpg." e.g. resulting in disclosure of local files. 2) Solution or Work-Around There is no known workaround, please install the update packages. 3) Special Instructions and Notes Please restart running instances of Opera 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 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/opera-8.50-2.1.i586.rpm 14d5e5fa885cdcbfe295bf14e78cc597 SUSE LINUX 9.2: ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/i586/opera-8.50-2.1.i586.rpm d49cde72a2ca0a577b1f46d642177a2c SUSE LINUX 9.1: ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/i586/opera-8.50-1.1.i586.rpm 37d049f6e1c74d93d53c8369e3c7d38a source rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/src/opera-8.50-1.1.nosrc.rpm d186e1294cee84c3472df1ac84a3d6a2 SuSE Linux 9.0: ftp://ftp.suse.com/pub/suse/i386/update/9.0/rpm/i586/opera-8.50-3.i586.rpm c9e8a2b20726590afafed2acf33878e5 source rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.0/rpm/src/opera-8.50-3.nosrc.rpm ba618d920bd3c67198a6cfe81417f505 SUSE LINUX OSS 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/i586/opera-8.50-2.1.i586.rpm f6fd16f597c24c44ff22d3079d67bf04 source rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/src/opera-8.50-2.1.nosrc.rpm f4d1a6f0d53de4d0a3c66342b39a1090 x86-64 Platform: SUSE LINUX 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/x86_64/opera-8.50-2.1.x86_64.rpm 5e7cc77dffeeb6f7f49040fe57a24436 source rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/src/opera-8.50-2.1.nosrc.rpm 51bdcf29e4838f37c513db2fda7ce4cb SUSE LINUX 9.2: ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/x86_64/opera-8.50-2.1.x86_64.rpm 92ae1f3adca409fc7504f75eb9a048cd source rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/src/opera-8.50-2.1.nosrc.rpm 0068542ea265d222909b1a7afb2efd5d SUSE LINUX 9.1: ftp://ftp.suse.com/pub/suse/x86_64/update/9.1/rpm/x86_64/opera-8.50-1.1.x86_64.rpm 26e585d3cd1b813a5fc5905d00ea8c41 source rpm(s): ftp://ftp.suse.com/pub/suse/x86_64/update/9.1/rpm/src/opera-8.50-1.1.nosrc.rpm e1d6ab204a6b53257f883e0319001862 SuSE Linux 9.0: ftp://ftp.suse.com/pub/suse/x86_64/update/9.0/rpm/x86_64/opera-8.50-3.x86_64.rpm eb553979fd5085a91fa2d31faff03f8f source rpm(s): ftp://ftp.suse.com/pub/suse/x86_64/update/9.0/rpm/src/opera-8.50-3.nosrc.rpm 6495e097ae44fb75e9db8407bc2ce793 SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/opera-8.50-2.1.x86_64.rpm 150053c82d63a0e33472eaa656417b32 source rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/src/opera-8.50-2.1.nosrc.rpm db1da6ab611d0c70f46602585d0868d4 ______________________________________________________________________________ 5) Pending Vulnerabilities, Solutions, and Work-Arounds: See SUSE Security Summary Report. ______________________________________________________________________________ 6) Authenticity Verification and Additional Information - Announcement authenticity verification: SUSE security announcements are published via mailing lists and on Web sites. 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>. For general information or the frequently asked questions (FAQ), send mail to <suse-security-info@suse.com> or <suse-security-faq@suse.com>. ===================================================================== SUSE's security contact is <security@suse.com> or <security@suse.de>.
