1) Problem Description and Brief Discussion
IBM Java 6 SR 5 was released fixing various bugs and critical security issues:
CVE-2009-1093: A vulnerability in the Java Runtime Environment (JRE) with initializing LDAP connections may be exploited by a remote client to cause a denial-of-service condition on the LDAP service.
CVE-2009-1094: A vulnerability in Java Runtime Environment LDAP client implementation may allow malicious data from an LDAP server to cause malicious code to be unexpectedly loaded and executed on an LDAP client.
CVE-2009-1095 CVE-2009-1096: Buffer overflow vulnerabilities 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-2009-1097: A buffer overflow vulnerability in the Java Runtime Environment with processing PNG images 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-2009-1097: A buffer overflow vulnerability in the Java Runtime Environment with processing GIF images 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-2009-1098: A buffer overflow vulnerability in the Java Runtime Environment with processing GIF images 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-2009-1099: A buffer overflow vulnerability in the Java Runtime Environment 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-2009-1100: A vulnerability in the Java Runtime Environment (JRE) with storing temporary font files may allow an untrusted applet or application to consume a disproportionate amount of disk space resulting in a denial-of-service condition.
CVE-2009-1100: A vulnerability in the Java Runtime Environment (JRE) with processing temporary font files may allow an untrusted applet or application to retain temporary files resulting in a denial-of-service condition.
CVE-2009-1101: A vulnerability in the Java Runtime Environment (JRE) HTTP server implementation may allow a remote client to create a denial-of-service condition on a JAX-WS service endpoint that runs on the JRE.
CVE-2009-1103: A vulnerability in the Java Plug-in with deserializing applets may allow an untrusted applet 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-2009-1106: A vulnerability in the Java Runtime Environment with parsing crossdomain.xml files may allow an untrusted applet to connect to any site that provides a crossdomain.xml file instead of sites that allow the domain that the applet is running on.
CVE-2009-1107: The Java Plugin displays a warning dialog for signed applets. A signed applet can obscure the contents of the dialog and trick a user into trusting the applet.
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 IBM Java 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.
Our maintenance customers are notified individually. The packages are offered for installation from the maintenance web:

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 firstname.lastname@example.org"
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 <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 email@example.com 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:
firstname.lastname@example.org - General Linux and SUSE security discussion. All SUSE security announcements are sent to this list. To subscribe, send an e-mail to email@example.com.
firstname.lastname@example.org - SUSE's announce-only mailing list. Only SUSE's security announcements are sent to this list. To subscribe, send an e-mail to email@example.com.
