RHSA-2007:0956: java-1.5.0-bea security update

Description

Updated java-1.5.0-bea packages that correct several security issues are now available for Red Hat Enterprise Linux 4 Extras and 5 Supplementary. This update has been rated as having moderate security impact by the Red Hat Security Response Team.

The BEA WebLogic JRockit 1.5.0_11 JRE and SDK contain BEA WebLogic JRockit Virtual Machine 1.5.0_11 and are certified for the Java 5 Platform, Standard Edition, v1.5.0. A flaw was found in the BEA Java Runtime Environment GIF image handling. If an application processes untrusted GIF image input, it may be possible to execute arbitrary code as the user running the Java Virtual Machine. (CVE-2007-0243) A buffer overflow in the Java Runtime Environment image handling code was found. If an attacker is able to cause a server application to process a specially crafted image file, it may be possible to execute arbitrary code as the user running the Java Virtual Machine. (CVE-2007-2788, CVE-2007-2789, CVE-2007-3004) A denial of service flaw was discovered in the Java Applet Viewer. An untrusted Java applet could cause the Java Virtual Machine to become unresponsive. Please note that the BEA WebLogic JRockit 1.5.0_11 does not ship with a browser plug-in and therefore this issue could only be triggered by a user running the "appletviewer" application. (CVE-2007-3005) A cross site scripting (XSS) flaw was found in the Javadoc tool. An attacker could inject arbitrary content into a Javadoc generated HTML documentation page, possibly tricking a user or stealing sensitive information. (CVE-2007-3503) A denial of service flaw was found in the way the JSSE component processed SSL/TLS handshake requests. A remote attacker able to connect to a JSSE enabled service could send a specially crafted handshake which would cause the Java Runtime Environment to stop responding to future requests. (CVE-2007-3698) A flaw was found in the way the Java Runtime Environment processes font data. An applet viewed via the 'appletviewer' application could elevate its privileges, allowing the applet to perform actions with the same permissions as the user running the "appletviewer" application. It may also be possible to crash a server application which processes untrusted font information from a third party. (CVE-2007-4381) All users of java-bea-1.5.0 should upgrade to these updated packages, which contain the BEA WebLogic JRockit 1.5.0_11 release that resolves these issues.
