The update fixes the following security problems: CVE-2008-5350: A security vulnerability in the Java Runtime Environment (JRE) may allow an untrusted applet or application to list the contents of the home directory of the user running the applet or application. CVE-2008-5346: A security vulnerability in the Java Runtime Environment (JRE) with parsing zip files may allow an untrusted applet or application to read arbitrary memory locations in the process that the applet or application is running in. CVE-2008-5343: A vulnerability in Java Web Start and Java Plug-in may allow hidden code on a host to make network connections to that host and to hijack HTTP sessions using cookies stored in the browser. CVE-2008-5344: A vulnerability in the Java Runtime Environment (JRE) with applet classloading may allow an untrusted applet to read arbitrary files on a system that the applet runs on and make network connections to hosts other than the host it was loaded from. CVE-2008-5359: A buffer overflow vulnerability in the Java Runtime Environment (JRE) image processing code may allow an untrusted applet or application to escalate privileges. For example, an untrusted applet may grant itself permissions to read and write local files or execute local applications that are accessible to the user running the untrusted applet. CVE-2008-5341: A vulnerability in the Java Runtime Environment may allow an untrusted Java Web Start application to determine the location of the Java Web Start cache and the user name of the user running the Java Web Start application. CVE-2008-5339: A vulnerability in the Java Runtime Environment (JRE) may allow an untrusted Java Web Start application to make network connections to hosts other than the host that the application is downloaded from. CVE-2008-5340: A vulnerability in the Java Runtime Environment with launching Java Web Start applications may allow an untrusted Java Web Start application to escalate privileges. For example, an untrusted application may grant itself permissions to read and write local files or execute local applications that are accessible to the user running the untrusted application. CVE-2008-5348: A security vulnerability in the Java Runtime Environment (JRE) with authenticating users through Kerberos may lead to a Denial of Service (DoS) to the system as a whole, due to excessive consumption of operating system resources. CVE-2008-2086: A vulnerability in Java Web Start may allow certain trusted operations to be performed, such as modifying system properties. CVE-2008-5345: The Java Runtime Environment (JRE) allows code loaded from the local filesystem to access localhost. This may allow code that is maliciously placed on the local filesystem and then subsequently run, to have network access to localhost that would not otherwise be allowed if the code were loaded from a remote host. This may be leveraged to steal cookies and hijack sessions (for domains that map a name to the localhost). CVE-2008-5351: The UTF-8 (Unicode Transformation Format-8) decoder in the Java Runtime Environment (JRE) accepts encodings that are longer than the "shortest" form. This behavior is not a vulnerability in Java SE. However, it may be leveraged to exploit systems running software that relies on the JRE UTF-8 decoder to reject non-shortest form sequences. For example, non-shortest form sequences may be decoded into illegal URIs, which may then allow files that are not otherwise accessible to be read, if the URIs are not checked following UTF-8 decoding. CVE-2008-5360: The Java Runtime Environment creates temporary files with insufficiently random names. This may be leveraged to write JAR files which may then be loaded as untrusted applets and Java Web Start applications to access and provide services from localhost and hence steal cookies. CVE-2008-5353: A security vulnerability in the Java Runtime Environment (JRE) related to deserializing calendar objects may allow an untrusted applet or application to escalate privileges. For example, an untrusted applet may grant itself permissions to read and write local files or execute local applications that are accessible to the user running the untrusted applet. CVE-2008-5356: A buffer vulnerability in the Java Runtime Environment (JRE) with processing fonts may allow an untrusted applet or Java Web Start application to escalate privileges. For example, an untrusted applet may grant itself permissions to read and write local files or execute local applications that are accessible to the user running the untrusted applet. CVE-2008-5354: A buffer overflow vulnerability in the Java Runtime Environment (JRE) may allow an untrusted Java application that is launched through the command line to escalate privileges. For example, the untrusted Java application may grant itself permissions to read and write local files or execute local applications that are accessible to the user running the untrusted Java application. This vulnerability cannot be exploited by an applet or Java Web Start application. CVE-2008-5357: A buffer vulnerability in the Java Runtime Environment (JRE) with processing fonts may allow an untrusted applet or Java Web Start application to escalate privileges. For example, an untrusted applet may grant itself permissions to read and write local files or execute local applications that are accessible to the user running the untrusted applet. CVE-2008-5352: A buffer overflow vulnerability in the Java Runtime Environment (JRE) with unpacking applets and Java Web Start applications using the "unpack200" JAR unpacking utility may allow an untrusted applet or application to escalate privileges. For example, an untrusted applet may grant itself permissions to read and write local files or execute local applications that are accessible to the user running the untrusted applet. CVE-2008-5342: A security vulnerability in the the Java Web Start BasicService allows untrusted applications that are downloaded from another system to request local files to be displayed by the browser of the user running the untrusted application.

While letting them run will usually work, they for instance lose access to dynamically loaded information like timezone data. 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. Our maintenance customers are notified individually. The packages are offered for installation from the maintenance web: SUSE Linux Enterprise Server 10 SP2 http://download.novell.com/index.jsp?search=Search&keywords=9a91147409995ade2d60bff341961c31 SUSE Linux Enterprise Desktop 10 SP2 http://download.novell.com/index.jsp?search=Search&keywords=9a91147409995ade2d60bff341961c31 Open Enterprise Server http://download.novell.com/index.jsp?search=Search&keywords=8671eb8081c281a0c30b3955c9f0a7b6 Novell Linux POS 9 http://download.novell.com/index.jsp?search=Search&keywords=8671eb8081c281a0c30b3955c9f0a7b6 SUSE SLES 9 http://download.novell.com/index.jsp?search=Search&keywords=8671eb8081c281a0c30b3955c9f0a7b6 ______________________________________________________________________________ 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. 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. - SUSE runs two security mailing lists to which any interested party may subscribe: opensuse-security@opensuse.org - General Linux and SUSE security discussion.
