Sun Java Runtime Environment (JRE) 1.5.0_6 and earlier, JDK 1.5.0_6 and earlier, and SDK 1.5.0_6 and earlier allows remote attackers to cause a denial of service (disk consumption) by using the Font.createFont function to create temporary files of arbitrary size in the %temp% directory.

From Red Hat Security Advisory 2009:0377 :

Updated java-1.6.0-openjdk packages that fix several security issues 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 that the Java Virtual Machine (JVM) handled temporary font files. A malicious applet could use this flaw to use large amounts of disk space, causing a denial of service.
(CVE-2006-2426)

A memory leak flaw was found in LittleCMS (embedded in OpenJDK). An application using color profiles could use excessive amounts of memory, and possibly crash after using all available memory, if used to open specially crafted images. (CVE-2009-0581)

Multiple integer overflow flaws which could lead to heap-based buffer overflows, as well as multiple insufficient input validation flaws, were found in the way LittleCMS handled color profiles. An attacker could use these flaws to create a specially crafted image file which could cause a Java application to crash or, possibly, execute arbitrary code when opened. (CVE-2009-0723, CVE-2009-0733)

A NULL pointer dereference flaw was found in LittleCMS. An application using color profiles could crash while converting a specially crafted image file. (CVE-2009-0793)

A flaw in the Java API for XML Web Services (JAX-WS) service endpoint handling could allow a remote attacker to cause a denial of service on the server application hosting the JAX-WS service endpoint.
(CVE-2009-1101)

A flaw in the way the Java Runtime Environment initialized LDAP connections could allow a remote, authenticated user to cause a denial of service on the LDAP service. (CVE-2009-1093)

A flaw in the Java Runtime Environment LDAP client could allow malicious data from an LDAP server to cause arbitrary code to be loaded and then run on an LDAP client. (CVE-2009-1094)

Several buffer overflow flaws were found in the Java Runtime Environment unpack200 functionality. An untrusted applet 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. (CVE-2009-1095, CVE-2009-1096)

A flaw in the Java Runtime Environment Virtual Machine code generation functionality could allow untrusted applets to extend their privileges. An untrusted applet could extend its privileges, allowing it to read and write local files, as well as execute local applications with the privileges of the user running the applet.
(CVE-2009-1102)

A buffer overflow flaw was found in the splash screen processing. A remote attacker could extend privileges to read and write local files, as well as to execute local applications with the privileges of the user running the java process. (CVE-2009-1097)

A buffer overflow flaw was found in how GIF images were processed. A remote attacker could extend privileges to read and write local files, as well as execute local applications with the privileges of the user running the java process. (CVE-2009-1098)

Note: The flaws concerning applets in this advisory, CVE-2009-1095, CVE-2009-1096, and CVE-2009-1102, can only be triggered in java-1.6.0-openjdk by calling the 'appletviewer' application.

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.

The version of Sun Java Runtime Environment (JRE) installed on the remote host is earlier than 6 Update 13 / 5.0 Update 18 / 1.4.2_20 / 1.3.1_25.  Such versions are potentially affected by the following security issues :

  - A denial of service vulnerability affects the JRE LDAP     implementation. (254569).

  - A remote code execution vulnerability in the JRE LDAP     implementation may allow for arbitrary code to be run in     the context of the affected LDAP client. (254569)

  - There are multiple integer and buffer overflow     vulnerabilities when unpacking applets and Java Web     Start applications using the 'unpack2000' utility.
    (254570)

  - There are multiple denial of service vulnerabilities     related to the storing and processing of temporary font     files. (254608)

  - A privilege escalation vulnerability affects the Java     Plug-in when deserializing applets. (254611)

  - A weakness in the Java Plug-in allows JavaScript loaded     from the localhost to connect to arbitrary ports on the     local system. (254611)

  - A vulnerability in the Java Plug-in allows malicious     JavaScript code to exploit vulnerabilities in earlier     versions of the JRE that have been loaded by an applet     located on the same web page. (254611)

  - An issue exists in the Java Plug-in when parsing     'crossdomain.xml' allows an untrusted applet to connect     to an arbitrary site hosting a 'crossdomain.xml' file.
    (254611)

  - The Java Plug-in allows a malicious signed applet to     obscure the contents of a security dialog. (254611)

  - The JRE Virtual Machine is affected by a     privilege escalation vulnerability. (254610)

  - There are multiple buffer overflow vulnerabilities     involving the JRE's processing of PNG and GIF images.
    (254571)

  - There are multiple buffer overflow vulnerabilities     involving the JRE's processing of fonts. (254571)

  - A denial of service vulnerability affected the JRE HTTP     server implementation, which could be used to cause a     denial of service on a JAX-WS service endpoint. (254609)

This update fixes several vulnerabilities in the Sun Java 6 Runtime Environment and the Sun Java 6 Software Development Kit. These vulnerabilities are summarized on the 'Advance notification of Security Updates for Java SE' page from Sun Microsystems, listed in the References section.

All running instances of Sun Java must be restarted for the update to take effect.

Note: jdk-1.6.0_13-fcs.x86_64.rpm could not be signed. All other rpm's are signed with the usual signature.

Updated java-1.5.0-sun packages that correct several security issues are now available for Red Hat Network Satellite Server 5.1.

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

This update corrects several security vulnerabilities in the Sun Java Runtime Environment shipped as part of Red Hat Network Satellite Server 5.1. In a typical operating environment, these are of low security risk as the runtime is not used on untrusted applets.

Several flaws were fixed in the Sun Java 5 Runtime Environment.
(CVE-2006-2426, CVE-2008-2086, CVE-2009-1093, CVE-2009-1094, CVE-2009-1095, CVE-2009-1096, CVE-2009-1098, CVE-2009-1099, CVE-2009-1100, CVE-2009-1103, CVE-2009-1104, CVE-2009-1107, CVE-2009-2409, CVE-2009-2475, CVE-2009-2625, CVE-2009-2670, CVE-2009-2671, CVE-2009-2672, CVE-2009-2673, CVE-2009-2675, CVE-2009-2676, CVE-2009-2689, CVE-2009-3728, CVE-2009-3873, CVE-2009-3876, CVE-2009-3877, CVE-2009-3879, CVE-2009-3880, CVE-2009-3881, CVE-2009-3882, CVE-2009-3883, CVE-2009-3884)

Note: This is the final update for the java-1.5.0-sun packages, as the Sun Java SE Release family 5.0 has now reached End of Service Life. An alternative to Sun Java SE 5.0 is the Java 2 Technology Edition of the IBM Developer Kit for Linux, which is available from the Satellite 5.1 channels on the Red Hat Network.

For a long term solution, Red Hat advises users to switch from Sun Java SE 5.0 to the Java 2 Technology Edition of the IBM Developer Kit for Linux. Refer to the Solution section for instructions.
