Critical: java-1.4.2-ibm security update

Updated java-1.4.2-ibm packages that fix several security issues are now
available for Red Hat Enterprise Linux 3 and 4 Extras, and 5
Supplementary.

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

IBM's 1.4.2 SR10 Java release includes the IBM Java 2 Runtime Environment
and the IBM Java 2 Software Development Kit.

The Java Secure Socket Extension (JSSE) component did not correctly process
SSL/TLS handshake requests. A remote attacker who is able to connect to a
JSSE-based service could trigger this flaw leading to a denial-of-service.
(CVE-2007-3698)

A flaw was found in the way the Java Runtime Environment processes font
data. An untrusted applet could elevate its privileges, allowing the applet
to perform actions with the same permissions as the logged in user. It may
also be possible to crash a server application which processes untrusted
font information from a third party. (CVE-2007-4381)

The applet caching mechanism of the Java Runtime Environment (JRE) did not
correctly process the creation of network connections. A remote attacker
could use this flaw to create connections to services on machines other
than the one that the applet was downloaded from. (CVE-2007-5232)

Multiple vulnerabilities existed in Java Web Start allowing an untrusted
application to determine the location of the Java Web Start cache.
(CVE-2007-5238)

Untrusted Java Web Start Applications or Java Applets were able to drag and
drop a file to a Desktop Application. A user-assisted remote attacker could
use this flaw to move or copy arbitrary files. (CVE-2007-5239)

The Java Runtime Environment allowed untrusted Java Applets or applications
to display oversized Windows. This could be used by remote attackers to
hide security warning banners. (CVE-2007-5240)

Unsigned Java Applets communicating via a HTTP proxy could allow a remote
attacker to violate the Java security model. A cached malicious Applet
could create network connections to services on other machines.
(CVE-2007-5273)

Unsigned Applets loaded with Mozilla Firefox or Opera browsers allowed
remote attackers to violate the Java security model. A cached malicious
Applet could create network connections to services on other machines.
(CVE-2007-5274)

All users of java-1.4.2-ibm are advised to upgrade to these updated
packages, that contain IBM's 1.4.2 SR10 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.
