Updated icedtea-web packages that fix one security issue are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having critical security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The IcedTea-Web project provides a Java web browser plug-in and an implementation of Java Web Start, which is based on the Netx project.
It also contains a configuration tool for managing deployment settings for the plug-in and Web Start implementations.

A buffer overflow flaw was found in the IcedTea-Web plug-in. Visiting a malicious web page could cause a web browser using the IcedTea-Web plug-in to crash or, possibly, execute arbitrary code. (CVE-2012-4540)

Red Hat would like to thank Arthur Gerkis for reporting this issue.

This erratum also upgrades IcedTea-Web to version 1.2.2. Refer to the NEWS file, linked to in the References, for further information.

All IcedTea-Web users should upgrade to these updated packages, which resolve this issue. Web browsers using the IcedTea-Web browser plug-in must be restarted for this update to take effect.

The IcedTea-Web Java plugin has been updated to version 1.3.1 to fix various bugs and security issues.

1.3.1 changes :

  - Security Updates

  - RH869040: Heap-based buffer overflow after triggering     event attached to applet. (CVE-2012-4540)

  - Common

  - PR1161: X509VariableTrustManager does not work correctly     with OpenJDK7 fixes the self-signed issue (mentioned in     bnc#784859, bnc#785333, bnc#786775)

The remote Oracle Linux 6 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2012-1434 advisory.

    [1.2.2-1]
    - Updated to 1.2.2
    - Resolves: CVE-2012-4540

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

A heap-based buffer overflow vulnerability was found in icedtea-web, a web browser plugin for running applets written in the Java programming language. If a user were tricked into opening a malicious website, an attacker could cause the plugin to crash or possibly execute arbitrary code as the user invoking the program.

This problem was initially discovered by Arthur Gerkis and got assigned CVE-2012-4540. Fixes where applied in the 1.1, 1.2 and 1.3 branches but not to the 1.4 branch.
