The Java Network Launching Protocol (JNLP) implementation in IcedTea6 1.9.x before 1.9.9 and before 1.8.9, and IcedTea-Web 1.1.x before 1.1.1 and before 1.0.4, allows remote attackers to obtain the username and full path of the home and cache directories by accessing properties of the ClassLoader.

This update of icedtea/icedtea-web fixes two issues :

  - CVE-2011-2513: CVSS v2 Base Score: 4.3: An information     leak allows unsigned Web Start applications to determine     the path to the cache directory used to store downloaded     class and jar files.

  - CVE-2011-2514: CVSS v2 Base Score: 5.1 An unsigned Web     Start application could manipulate content of the     security warning dialog message to show different file     name in prompts.

From Red Hat Security Advisory 2011:1100 :

Updated icedtea-web packages that fix two security issues are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links 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 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.

Omair Majid discovered that an unsigned Web Start application or applet could determine the path to the cache directory used to store downloaded class and jar files by querying class loader properties.
This could allow a remote attacker to discover a user's name and home directory path. (CVE-2011-2513)

Omair Majid discovered that an unsigned Web Start application could manipulate the content of the security warning dialog message to show different file names in prompts. This could allow a remote attacker to confuse a user into granting access to a different file than they believe they are granting access to. This issue only affected Ubuntu 11.04. (CVE-2011-2514).

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2011:1100 advisory.

  - icedtea, icedtea-web: home directory path disclosure to untrusted applications (CVE-2011-2513)

  - icedtea-web: Java Web Start security warning dialog manipulation (CVE-2011-2514)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

This security fix that addresses the following issues :

  - RH718164: Home directory path disclosure to untrusted     applications

    - RH718170: Java Web Start security warning dialog       manipulation
