Package: opera Announcement ID: SUSE-SA:2007:009 Date: Mon, 15 Jan 2007 12:00:00 +0000 Affected Products: openSUSE 10.2 SUSE LINUX 10.1 SUSE LINUX 10.0 SUSE LINUX 9.3 Vulnerability Type: remote code execution Severity (1-10): 7 SUSE Default Package: yes Cross-References: CVE-2007-0126, CVE-2007-0127

Content of This Advisory: 1) Security Vulnerability Resolved: opera 9.10 security upgrade 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 brings the Opera Web browser to version 9.10, including fixes for the following 2 security problems:

- CVE-2007-0126: Opera processes a JPEG DHT marker incorrectly, which can potentially lead to remote code execution.

- CVE-2007-0127: Opera is affected by a typecasting bug in its Javascripts SVG implementation which could potentially be used to execute code.

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 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.

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:

opensuse-security@opensuse.org - General Linux and SUSE security discussion. All SUSE security announcements are sent to this list. To subscribe, send an e-mail to opensuse-security+subscribe@opensuse.org.

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.
