This allowed man-in-the-middle attackers to inject HTTP requests in a HTTPS session without being noticed. For example Apache's mod_ssl was vulnerable to this kind of attack because it uses openssl. It is believed that this vulnerability is actively exploited in the wild to get access to HTTPS protected web-sites. Please note that renegotiation will be disabled for any application using openssl by this update and may cause problems in some cases. Additionally this attack is not limited to HTTP. 2) Solution or Work-Around There is no work-around known. Please install the update. Moblin packages will be released later. 3) Special Instructions and Notes Please note that this update disables renegotiation for all applications using openssl. All applications using openssl need to be restarted. You can find out what library an application uses with lsof(8) as root. If possible restart your system. 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 inSection 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 11.2:

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 replacing with the name of the file where you saved the announcement. The output for a valid signature looks like: gpg: Signature made using RSA key ID 3D25D3D9 gpg: Good signature from "SuSE Security Team " where 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. 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 theRPM package downloaded. The package is unmodified if it contains a valid signature from This email address is being protected from spambots. You need JavaScript enabled to view it. 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. - SUSE runs two security mailing lists to which any interested party may subscribe: This email address is being protected from spambots.
