Description

CentOS Errata and Security Advisory CESA-2012:1132

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.

An uninitialized pointer use flaw was found in the IcedTea-Web plug-in. Visiting a malicious web page could possibly cause a web browser using the IcedTea-Web plug-in to crash, disclose a portion of its memory, or execute arbitrary code. (CVE-2012-3422)

It was discovered that the IcedTea-Web plug-in incorrectly assumed all strings received from the browser were NUL terminated. When using the plug-in with a web browser that does not NUL terminate strings, visiting a web page containing a Java applet could possibly cause the browser to crash, disclose a portion of its memory, or execute arbitrary code. (CVE-2012-3423)

Red Hat would like to thank Chamal De Silva for reporting the CVE-2012-3422 issue.

This erratum also upgrades IcedTea-Web to version 1.2.1. 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 these issues. Web browsers using the IcedTea-Web browser plug-in must be restarted for this update to take effect.
