(Mandrake Issues Fix) KDE Konqueror Java Bugs Let Remote Users Access Restricted Java Classes
SecurityTracker Alert ID:  1012693
SecurityTracker URL:  http://securitytracker.com/id/1012693
CVE Reference:   CVE-2004-1145   (Links to External Site)
Date:  Dec 24 2004
Impact:   Disclosure of system information, Disclosure of user information, Modification of system information, Modification of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 3.3.1 and prior versions
Description:   A vulnerability was reported in KDE Konqueror in the Java implementation. A remote user can bypass the Java sandbox security mechanism and can also gain access to certain restricted Java classes.

The vendor reported that a remote user can create JavaScript that, when loaded by the target user, will be able to bypass the Java sandbox security mechanisms and access restricted Java classes. Also, a remote user can create Java code that, when loaded by the target user, can access certain Java classes that it should not be able to access.

In both cases, the applet may be able to obtain elevated privileges to read and write files with the privileges of the target user.

The vendor was notified on November 24, 2004.

heise Security is credited with reporting this flaw.

A demonstration exploit check is available at:

http://www.heise.de/security/dienste/browsercheck/tests/java.shtml

Impact:   A remote user can access to restricted Java classes to potentially read and write files on the target system with the privileges of the target user.
Solution:   Mandrake has released a fix.
