icedtea security update

CentOS Errata and Security Advisory CESA-2012:1434

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.
