(RHSA-2007:0963) Important: java-1.5.0-sun security update

The Java Runtime Environment (JRE) contains the software and tools
that users need to run applets and applications written using the Java
programming language.

A flaw in 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 (JRE) 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)

In Red Hat Enterprise Linux a Java Web Start application requesting
elevated permissions is only started automatically when signed with a
trusted code signing certificate and otherwise requires user confirmation
to access privileged resources.

All users of java-sun-1.5.0 should upgrade to these packages, which contain
Sun Java 1.5.0 Update 13 that corrects these issues.

Please note that during our quality testing we discovered that the Java
browser plug-in may not function perfectly when visiting some sites that
make use of multiple applets on a single HTML page. We have verified that
this issue is not due to our packaging and affects Sun Java 1.5.0 Update 13.
