Details will be disclosed at a later date. CVE-2007-6521: Fixed an issue with TLS certificates that could be used to execute arbitrary code, as reported by Alexander Klink (Cynops GmbH). Details will be disclosed at a later date. CVE-2007-6522: Rich text editing can no longer be used to allow cross domain scripting, as reported by David Bloom. See our advisory. CVE-2007-6523: Fixed a problem where malformed BMP files could cause Opera to temporarily freeze. CVE-2007-6524: Prevented bitmaps from revealing random data from memory, as reported by Gynvael Coldwind. Details will be disclosed at a later date. 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 to apply the update, replacing with the filename of the downloaded RPM package. x86 Platform: openSUSE 10.3: http://download.opensuse.org/pub/opensuse/update/10.3/rpm/i586/opera-9.25-1.... 1cc7dfa3230320e6f90d235fec6e885f openSUSE 10.2: ftp://ftp.suse.com/pub/suse/update/10.2/rpm/i586/opera-9.25-1.1.i586.rpm 8d66debcef68034bfc60344283009a2c SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/i586/opera-9.25-1.1.i586.rpm 2c437285b8cc80decb649ec818f5a616 Power PC Platform: openSUSE 10.3: http://download.opensuse.org/pub/opensuse/update/10.3/rpm/ppc/opera-9.25-1.1... 715ee156b5f5b3983ddc576e8f9b74d7 openSUSE 10.2: ftp://ftp.suse.com/pub/suse/update/10.2/rpm/ppc/opera-9.25-1.1.ppc.rpm d2496ef4adbffc6688ff720d6674d6a0 SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/ppc/opera-9.25-1.1.ppc.rpm 82aa04dc7743d43239b34dc115729942 x86-64 Platform: openSUSE 10.3: http://download.opensuse.org/pub/opensuse/update/10.3/rpm/x86_64/opera-9.25-... 799df7724aece868efdfe2474e137eef openSUSE 10.2: ftp://ftp.suse.com/pub/suse/update/10.2/rpm/x86_64/opera-9.25-1.1.x86_64.rpm 76c67616c8d2c70f77b43935832c44d4 SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/x86_64/opera-9.25-1.1.x86_64.rpm 75de97d12c071a60f498f84536d8be29 Sources: openSUSE 10.3: http://download.opensuse.org/pub/opensuse/update/10.3/rpm/src/opera-9.25-1.1... 157c00c3e60dd9610521b9b050cfaaac openSUSE 10.2: ftp://ftp.suse.com/pub/suse/update/10.2/rpm/src/opera-9.25-1.1.nosrc.rpm a628b5553b4306136f10e90217beb2c8 SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/src/opera-9.25-1.1.nosrc.rpm c5b73df479db77b4cb6819a0936f87e4 ______________________________________________________________________________ 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 " 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 to verify the signature of the package, replacing 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 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-announce@opensuse.org - SUSE's announce-only mailing list.
