RHSA-2007:0963: java-1.5.0-sun security update



Updated java-1.5.0-sun packages that correct several security issues are now available for Red Hat Enterprise Linux 4 Extras and 5 Supplementary. This update has been rated as having important security impact by the Red Hat Security Response Team.

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.
