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. IcedTea-Web now also contains

PolicyEditor - a simple tool to configure Java policies.

 

The following packages have been upgraded to a newer upstream version:

icedtea-web (1.6.2). (BZ#1275523)

 

Security Fix(es):

 

* It was discovered that IcedTea-Web did not properly sanitize applet URLs

when storing applet trust settings. A malicious web page could use this

flaw to inject trust-settings configuration, and cause applets to be

executed without user approval. (CVE-2015-5234)

 

* It was discovered that IcedTea-Web did not properly determine an applet's

origin when asking the user if the applet should be run. A malicious page

could use this flaw to cause IcedTea-Web to execute the applet without user

approval, or confuse the user into approving applet execution based on an

incorrectly indicated applet origin. (CVE-2015-5235)

 

Red Hat would like to thank Andrea Palazzo (Truel IT) for reporting these

issues.
