3. Description:

 

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.
