===================================================================== CERT-Renater Note d'Information No. 2007/VULN299 _____________________________________________________________________ DATE : 12/07/2007 HARDWARE PLATFORM(S) : / OPERATING SYSTEM(S) : Tout système avec Sun Java Runtime Environment ou Sun Java Development Kit ou Sun Java Software Development Kit ====================================================================== Sun(sm) Alert Notification * Sun Alert ID: 102934 * Synopsis: Security Vulnerabilities in the Java Runtime Environment Image Parsing Code May Allow a Untrusted Applet to Elevate Privileges * Category: Security * Product: Java 2 Platform, Standard Edition * BugIDs: 6483556, 6483560 * Avoidance: Patch, Upgrade * State: Resolved * Date Released: 31-May-2007, 29-Jun-2007 * Date Closed: 29-Jun-2007 * Date Modified: 29-Jun-2007, 10-Jul-2007 1. Impact A buffer overflow vulnerability in the image parsing code in the Java Runtime Environment may allow an untrusted applet or application to elevate its privileges. For example, an applet may grant itself permissions to read and write local files or execute local applications that are accessible to the user running the untrusted applet. A second vulnerability may allow an untrusted applet or application to cause the Java Virtual Machine to hang. Sun acknowledges, with thanks, Chris Evans of the Google Security Team, for bringing these issues to our attention. These issues are also referenced in the following documents: CVE-2007-2788 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-2788 CVE-2007-2789 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-2789 2. Contributing Factors These issues can occur in the following releases (for Windows, Solaris, and Linux): First vulnerability: * JDK and JRE 6 * JDK and JRE 5.0 Update 10 and earlier * SDK and JRE 1.4.2_14 and earlier * SDK and JRE 1.3.1_20 and earlier Second vulnerability: * JDK and JRE 6 * JDK and JRE 5.0 Update 10 and earlier * SDK and JRE 1.4.2_14 and earlier * SDK and JRE 1.3.1_19 and earlier To determine the default version of the JRE on a system for Solaris and Linux, the following command can be run: % java -version Note: The above command only determines the default version. Other versions may also be installed on the system. To determine the default version of the JRE on a system for Windows: 1. Click "Start" 2. Select "Run" 3. Type "cmd" (starts a command-line) 4. At the prompt, type "java -version" Note: The above command only determines the default version. Other versions may also be installed on the system. 3. Symptoms There are no reliable symptoms that would show the described issues have been exploited. 4. Relief/Workaround There is no workaround for this issue. Please see the Resolution section below. 5.
