Critical: java-1.6.0-ibm security update

Updated java-1.6.0-ibm packages that fix several security issues are now
available for Red Hat Enterprise Linux 5 Supplementary.

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

IBM's 1.6.0 Java release includes the IBM Java 2 Runtime Environment, and
the IBM Java 2 Software Development Kit.

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-2008-1191, 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 possibly 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 access local network services. (CVE-2008-1195)

All users of java-1.6.0-ibm are advised to upgrade to these updated
packages, that contain IBM's 1.6.0 SR1 Java release, which resolves these
issues.

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