Background ========== Sun's JDK and JRE provide interpreters for Java Applets in a sandboxed environment. These implementations provide the Java Web Start technology that can be used for easy client-side deployment of Java applications. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-java/sun-jdk < 1.4.2.10 >= 1.4.2.10 2 dev-java/sun-jre-bin < 1.4.2.10 >= 1.4.2.10 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== Applets executed using JRE or JDK can use "reflection" APIs functions to elevate its privileges beyond the sandbox restrictions. Adam Gowdiak discovered five vulnerabilities that use this method for privilege escalation. Two more vulnerabilities were discovered by the vendor. Peter Csepely discovered that Web Start Java applications also can an escalate their privileges. Impact ====== A malicious Java applet can bypass Java sandbox restrictions and hence access local files, connect to arbitrary network locations and execute arbitrary code on the user's machine. Java Web Start applications are affected likewise. Workaround ========== Select another Java implementation using java-config. Resolution ========== All Sun JDK users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-java/sun-jdk-1.4.2.10" All Sun JRE users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-java/sun-jre-bin-1.4.2.10" References ========== [ 1 ] Sun Security Alert ID 102170 http://sunsolve.sun.com/search/document.do?assetkey=1-26-102170-1 [ 2 ] Sun Security Alert ID 102171 http://sunsolve.sun.com/search/document.do?assetkey=1-26-102171-1 [ 3 ] CVE-2006-0614 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-0614 [ 4 ] CVE-2006-0615 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-0615 [ 5 ] CVE-2006-0616 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-0616 [ 6 ] CVE-2006-0617 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-0617 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200602-07.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
