RHEL 5 : java-1.6.0-openjdk (RHSA-2009:1201)

Critical Nessus Plugin ID 40510

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated java-1.6.0-openjdk packages that fix several security issues and a bug are now available for Red Hat Enterprise Linux 5.

This update has been rated as having important security impact by the Red Hat Security Response Team.

These packages provide the OpenJDK 6 Java Runtime Environment and the OpenJDK 6 Software Development Kit. The Java Runtime Environment (JRE) contains the software and tools that users need to run applications written using the Java programming language.

A flaw was found in the way the XML Digital Signature implementation in the JRE handled HMAC-based XML signatures. An attacker could use this flaw to create a crafted signature that could allow them to bypass authentication, or trick a user, applet, or application into accepting untrusted content. (CVE-2009-0217)

Several potential information leaks were found in various mutable static variables. These could be exploited in application scenarios that execute untrusted scripting code. (CVE-2009-2475)

It was discovered that OpenType checks can be bypassed. This could allow a rogue application to bypass access restrictions by acquiring references to privileged objects through finalizer resurrection.
(CVE-2009-2476)

A denial of service flaw was found in the way the JRE processes XML. A remote attacker could use this flaw to supply crafted XML that would lead to a denial of service. (CVE-2009-2625)

A flaw was found in the JRE audio system. An untrusted applet or application could use this flaw to gain read access to restricted System properties. (CVE-2009-2670)

Two flaws were found in the JRE proxy implementation. An untrusted applet or application could use these flaws to discover the usernames of users running applets and applications, or obtain web browser cookies and use them for session hijacking attacks. (CVE-2009-2671, CVE-2009-2672)

An additional flaw was found in the proxy mechanism implementation.
This flaw allowed an untrusted applet or application to bypass access restrictions and communicate using non-authorized socket or URL connections to hosts other than the origin host. (CVE-2009-2673)

An integer overflow flaw was found in the way the JRE processes JPEG images. An untrusted application could use this flaw to extend its privileges, allowing it to read and write local files, as well as to execute local applications with the privileges of the user running the application. (CVE-2009-2674)

An integer overflow flaw was found in the JRE unpack200 functionality.
An untrusted applet or application could extend its privileges, allowing it to read and write local files, as well as to execute local applications with the privileges of the user running the applet or application. (CVE-2009-2675)

It was discovered that JDK13Services grants unnecessary privileges to certain object types. This could be misused by an untrusted applet or application to use otherwise restricted functionality. (CVE-2009-2689)

An information disclosure flaw was found in the way private Java variables were handled. An untrusted applet or application could use this flaw to obtain information from variables that would otherwise be private. (CVE-2009-2690)

Note: The flaws concerning applets in this advisory, CVE-2009-2475, CVE-2009-2670, CVE-2009-2671, CVE-2009-2672, CVE-2009-2673, CVE-2009-2675, CVE-2009-2689, and CVE-2009-2690, can only be triggered in java-1.6.0-openjdk by calling the 'appletviewer' application.

This update also fixes the following bug :

* the EVR in the java-1.6.0-openjdk package as shipped with Red Hat Enterprise Linux allowed the java-1.6.0-openjdk package from the EPEL repository to take precedence (appear newer). Users using java-1.6.0-openjdk from EPEL would not have received security updates since October 2008. This update prevents the packages from EPEL from taking precedence. (BZ#499079)

All users of java-1.6.0-openjdk are advised to upgrade to these updated packages, which resolve these issues. All running instances of OpenJDK Java must be restarted for the update to take effect.

Solution

Update the affected packages.
