KDE Security Advisory: Konqueror Java VulnerabilityOriginal Release Date: 2004-12-20URL:http://www.kde.org/info/security/advisory-20041220-1.txt0. Referenceshttp://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-1145http://www.heise.de/security/dienste/browsercheck/tests/java.shtml1. Systems affected: All versions of KDE up to KDE 3.3.1 inclusive. KDE 3.3.2 is not affected.2. Overview: Two flaws in the Konqueror webbrowser make it possible to by pass the sandbox environment which is used to run Java-applets. One flaw allows access to restricted Java classes via JavaScript, making it possible to escalate the privileges of the Java-applet. The other problem is that Konqueror fails to correctly restrict access to certain Java classes from the Java-applet itself. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-1145 to this issue.3. Impact: When a user has Java enabled in Konqueror and visits a malicious website, the website can run a Java-applet and obtain escalated privileges allowing reading and writing of arbitrary files with the privileges of the user.4. Solution: Upgrade to KDE 3.3.2 A backport has been made available for older versions which fixes this vulnerability. Contact your OS vendor / binary package provider for information about how to obtain updated binary packages.5. Patch: For KDE 3.2.3 a backport of the new Java handling is available fromftp://ftp.kde.org/pub/kde/security_patches : 7fc001d010c640738ed7d2fe347f002d post-3.2.3-kdelibs-khtml-java.tar.bz26.
