Critical: java-1.5.0-ibm security update

Updated java-1.5.0-ibm packages that fix 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.

Two vulnerabilities in the Java Runtime Environment allowed an untrusted
application or applet to elevate the assigned privileges. This could be
misused by a malicious website to read and write local files or execute
local applications in the context of the user running the Java process.
(CVE-2008-0657)

A flaw was found in the Java XSLT processing classes. An untrusted
application or applet could cause a denial of service, or execute arbitrary
code with the permissions of the user running the JRE. (CVE-2008-1187)

Several buffer overflow flaws were found in Java Web Start (JWS). An
untrusted JNLP application could access local files or execute local
applications accessible to the user running the JRE.
(CVE-2008-1188, CVE-2008-1189, CVE-2008-1190, CVE-2008-1196)

A flaw was found in the Java Plug-in. A remote attacker could bypass the
same origin policy, executing arbitrary code with the permissions of the
user running the JRE. (CVE-2008-1192)

A flaw was found in the JRE image parsing libraries. An untrusted
application or applet could cause a denial of service, or possible execute
arbitrary code with the permissions of the user running the JRE.
(CVE-2008-1193)

A flaw was found in the JRE color management library. An untrusted
application or applet could trigger a denial of service (JVM crash).
(CVE-2008-1194)

The JRE allowed untrusted JavaScript code to create local network
connections by the use of Java APIs. A remote attacker could use these
flaws to acesss local network services. (CVE-2008-1195)

All users of java-ibm-1.5.0 are advised to upgrade to these updated
packages, that contain IBM's 1.5.0 SR7 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.
