Message-ID: <424332CD.8010809@gentoo.org> Date: Sun Jul 17 15:21:47 2005 From: koon at gentoo.org (Thierry Carrez) Subject: [gentoo-announce] [ GLSA 200503-28 ] Sun Java: Web Start argument injection vulnerability - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 200503-28 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - http://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: Normal Title: Sun Java: Web Start argument injection vulnerability Date: March 24, 2005 Bugs: #85804 ID: 200503-28 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======== Java Web Start JNLP files can be abused to evade sandbox restriction and execute arbitrary code. Background ========== Sun provides implementations of Java Development Kits (JDK) and Java Runtime Environments (JRE). 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 < 1.4.2.07 >= 1.4.2.07 < 1.4.2 2 dev-java/sun-jre-bin < 1.4.2.07 >= 1.4.2.07 < 1.4.2 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== Jouko Pynnonen discovered that Java Web Start contains a vulnerability in the way it handles property tags in JNLP files. Impact ====== By enticing a user to open a malicious JNLP file, a remote attacker could pass command line arguments to the Java Virtual machine, which can be used to bypass the Java "sandbox" and to execute arbitrary code with the permissions of the user running the application. Workaround ========== There is no known workaround at this time. Resolution ========== All Sun JDK users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-java/sun-jdk-1.4.2.07" All Sun JRE users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-java/sun-jre-bin-1.4.2.07" References ========== [ 1 ] Jouko Pynnonen advisory http://jouko.iki.fi/adv/ws.html [ 2 ] Sun Microsystems Alert Notification http://sunsolve.sun.com/search/document.do?assetkey=1-26-57740-1 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200503-28.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.
