> 1) Problem Description and Brief Discussion
>
> Miscalculation of a buffer size in the X Render extension of the
> X.Org X11 server could potentially be exploited by users to cause a
> buffer overflow and run code with elevated privileges.
>
> 2) Solution or Work-Around
>
> There is no known workaround, please install the update packages.
>
> 3) Special Instructions and Notes
>
> Please restart the X server by logging out or rebooting 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.

> 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
>
> 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.
>
> 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-at-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-at-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.
