Critical: java-1.5.0-ibm security update

Updated java-1.5.0-ibm packages that correct several security issues are
now available for Red Hat Enterprise Linux 4 Extras and 5 Supplementary.

This update has been rated as having critical security impact by the Red
Hat Security Response Team.

IBM's 1.5.0 Java release includes the IBM Java 2 Runtime Environment and
the IBM Java 2 Software Development Kit.

A security vulnerability in the Java Web Start component was discovered. An
untrusted application could elevate it's privileges, allowing it to read
and write local files that are accessible to the user running the Java Web
Start application. (CVE-2007-2435)

A buffer overflow in the Java Runtime Environment image handling code was
found. An untrusted applet or application could use this flaw to elevate
its privileges and potentially execute arbitrary code as the user running
the java virtual machine. (CVE-2007-2788, CVE-2007-2789, CVE-2007-3004)

An unspecified vulnerability was discovered in the Java Runtime
Environment. An untrusted applet or application could cause the java
virtual machine to become unresponsive. (CVE-2007-3005)

The Javadoc tool was able to generate HTML documentation pages that
contained cross-site scripting (XSS) vulnerabilities. A remote attacker
could use this to inject arbitrary web script or HTML. (CVE-2007-3503)

The Java Web Start URL parsing component contains a buffer overflow
vulnerability within the parsing code for JNLP files. A remote attacker
could create a malicious JNLP file that could trigger this flaw and execute
arbitrary code when opened. (CVE-2007-3655)

A flaw was found in the applet class loader. An untrusted applet could use
this flaw to circumvent network access restrictions, possibly connecting
to services hosted on the machine that executed the applet. (CVE-2007-3922)

All users of java-ibm-1.5.0 should upgrade to these updated packages, which
contain IBM's 1.5.0 SR5a Java release that resolves these issues.

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
