Java Web Start Bugs Let Remote Users Gain Privileges on the Target System
SecurityTracker Alert ID:  1020452
SecurityTracker URL:  http://securitytracker.com/id/1020452
CVE Reference:   CVE-2008-3111, CVE-2008-3112, CVE-2008-3113, CVE-2008-3114   (Links to External Site)
Updated:  Jul 10 2008
Original Entry Date:  Jul 9 2008
Impact:   Disclosure of system information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): prior to versions 6 Update 7, 5.0 Update 16, and 1.4.2_18
Description:   Several vulnerabilities were reported in Java Web Start. A remote user can read, write, and delete files and execute applications on the target user's system.

A remote user can create a specially crafted application that, when loaded by the target user, will trigger a buffer overflow and gain elevated privileges on the target user's system. This can be exploited to read and write files on the target user's system and execute applications on the target user's system with the privileges of the target user.

Other vulnerabilities allow a remote user to create arbitrary files on the target user's system, delete arbitrary files on the target user's system, and determine the location of the Java Web Start cache.

John Heasman of NGSSoftware reported one of these vulnerabilities. Peter Csepely reported one vulnerability via TippingPoint. An anonymous researcher reported one of these vulnerabilities via TippingPoint.

Impact:   A remote user can read, write, and delete files and execute applications on the target user's system with the privileges of the target user.
Solution:   Sun has issued the following fix.

* JDK and JRE 6 Update 7 or later
* JDK and JRE 5.0 Update 16 or later
