3. Problem description:
IBM's 1.5.0 Java release includes the IBM Java 2 Runtime Environment and
the IBM Java 2 Software Development Kit.
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-ibm-1.5.0 are advised to upgrade to these updated
packages, that contain IBM's 1.5.0 SR6 Java release which resolves these
issues.
4. Solution:
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.
