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.
A flaw was discovered in the JNLP (Java Network Launching Protocol)
implementation in IcedTea-Web. An unsigned Java Web Start application
could use this flaw to manipulate the content of a Security Warning
dialog box, to trick a user into granting the application unintended access
permissions to local files. (CVE-2011-2514)
An information disclosure flaw was discovered in the JNLP implementation in
IcedTea-Web. An unsigned Java Web Start application or Java applet could
use this flaw to determine the path to the cache directory used to store
downloaded Java class and archive files, and therefore determine the user's
login name. (CVE-2011-2513)
All icedtea-web users should upgrade to these updated packages, which
contain backported patches to correct these issues.
4. Solution:
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
