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 werediscovered 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 [ 2 ] Sun Security Alert ID 102171 [ 3 ] CVE-2006-0614 [ 4 ] CVE-2006-0615 [ 5 ] CVE-2006-0616 [ 6 ] CVE-2006-0617 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200602-07 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.

Background ========= Sun and Blackdown both provide implementations of the Java Development Kit (JDK) and Java Runtime Environment (JRE). Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-java/sun-jdk < 1.4.2.08 > = 1.4.2.08 2 dev-java/sun-jre-bin < 1.4.2.08 > = 1.4.2.08 3 dev-java/blackdown-jdk < 1.4.2.02 > = 1.4.2.02 4 dev-java/blackdown-jre < 1.4.2.02 > = 1.4.2.02 ------------------------------------------------------------------- 4 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description ========== Both Sun's and Blackdown's JDK and JRE may allow untrusted applets to elevate privileges. Impact ===== A remote attacker could embed a malicious Java applet in a web page and entice a victim to view it. This applet can then bypass security restrictions and execute any command or access any file with the rights of the user running the webbrowser. Workaround ========= There are no known workarounds at this time. Resolution ========= All Sun JDK users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose "> =dev-java/sun-jdk-1.4.2.08" All Sun JRE users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose "> =dev-java/sun-jre-bin-1.4.2.08" All Blackdown JDK users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose "> =dev-java/blackdown-jdk-1.4.2.02" All Blackdown JRE users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose "> =dev-java/blackdown-jre-1.4.2.02" Note to SPARC users: There is no stable secure Blackdown Java for the SPARC architecture. Affected users should remove the package until a SPARC package is released.
