(RHSA-2007:1041) Important: java-1.5.0-ibm security update

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.
