Description


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.
