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.
