Critical: java-1.5.0-ibm security update

java-1.5.0-ibm packages that correct a security issue are available for Red
Hat Enterprise Linux 5 Supplementary and Enterprise Linux 4 Extras.

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 flaw in GIF image handling was found in the SUN Java Runtime Environment
that has now been reported as also affecting IBM Java 2. An untrusted
applet or application could use this flaw to elevate its privileges and
potentially execute arbitrary code. (CVE-2007-0243)

This update also resolves the following issues:

* The java-1.5.0-ibm-plugin sub-package conflicted with the new
java-1.5.0-sun-plugin sub-package.

* The java-1.5.0-ibm-plugin package had incorrect dependencies. The
java-1.5.0-ibm-alsa package has been merged into the java-1.5.0-ibm package
to resolve this issue.

All users of java-ibm-1.5.0 should upgrade to these packages, which contain
IBM's 1.5.0 SR4 Java release which 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.
