Advisory Name: Java Web Start File Inclusion via System Properties Override
Release Date: 2008-12-03
Application: Sun Java Runtime Environment / Java Web Start
Versions: See below
Severity: High

I. BACKGROUND
Java Web Start (JWS) is a framework built by Sun that is used to run
Java applications outside of the browser. It is distributed with the
Java Runtime Environment (JRE) installation. JWS is typically launched
by clicking on a link in the browser and results in a separate process
being started that is not tied to the JVM inside the browser. In order
to accomplish this, the Java Network Launching Protocol (JNLP) is used
Problem Description:
Security issues were identified and fixed in openjdk (icedtea6)
and icedtea-web:
IcedTea6 prior to 1.10.4 allows remote untrusted Java Web Start
applications and untrusted Java applets to affect confidentiality
via unknown vectors related to Networking (CVE-2011-3547).
IcedTea6 prior to 1.10.4 allows remote untrusted Java Web Start

Multiple vulnerabilities have been discovered in Sun Java:
* Daniel Soeder discovered that a long codebase attribute string in a
JNLP file will overflow a stack variable when launched by Java
WebStart (CVE-2007-3655).
* Multiple vulnerabilities (CVE-2007-2435, CVE-2007-2788,
CVE-2007-2789) that were previously reported as GLSA 200705-23 and
GLSA 200706-08 also affect 1.4 and 1.6 SLOTs, which was not mentioned
in the initial revision of said GLSAs.

Web Start applications and untrusted Java applets to affect integrity
via unknown vectors related to Deserialization (CVE-2011-0865).
Multiple unspecified vulnerabilities in the Java Runtime Environment

29 and earlier, and 1.4.2_31 and earlier allow remote attackers
recommendation specifies an HMAC truncation length (HMACOutputLength)
but does not require a minimum for its length, which allows attackers
to spoof HMAC-based signatures and bypass authentication by specifying
a truncation length with a small number of bits (CVE-2009-0217).
The Java Web Start framework does not properly check all application
jar files trust and this allows context-dependent attackers to
execute arbitrary code via a crafted application, related to NetX
(CVE-2009-1896).

Unspecified vulnerability in the Java Runtime Environment (JRE)
in Oracle Java SE and Java for Business 6 Update 23 and earlier,
5.0 Update 27 and earlier, and 1.4.2_29 earlier allows remote
untrusted Java Web Start applications and untrusted Java applets to
affect integrity via unknown vectors related to Networking. NOTE: the
previous information was obtained from the February 2011 CPU. Oracle
has not commented on claims from a downstream vendor that this issue
involves DNS cache poisoning by untrusted applets. (CVE-2010-4448)

Bye bye my little 0day :(, Tavis Ormandy did a great job uncovering a
big logic flaw within Java JRE. I discovered that bug and other that
affects every browser few weeks ago and I posted the common "0day++" tweet.
The method in which Java Web Start support has been added to the JRE is
not less than a deliberately embedded backdoor(I really don't think so)
or a flagrant case of extreme negligence (+1).
It's even more incredible that Sun didn't assess the real risk of this
flaw after Tavis reported it to them.

The HTTP server implementation (sun.net.httpserver) contained an
unspecified denial of service vulnerability (CVE-2009-1101).
Several issues in Java Web Start have been addressed (CVE-2009-1095,
CVE-2009-1096, CVE-2009-1097, CVE-2009-1098). The Debian packages
currently do not support Java Web Start, so these issues are not
directly exploitable, but the relevant code has been updated
nevertheless.

A remote attacker could entice a user to open a specially crafted JAR
archive, applet, or Java Web Start application, possibly resulting in
the execution of arbitrary code with the privileges of the user running
the application. Furthermore, a remote attacker could cause a Denial of
Service affecting multiple services via several vectors, disclose
information and memory contents, write or execute local files, conduct
session hijacking attacks via GIFAR files, steal cookies, bypass the
Hi,
There is vulnerability in Java Web Start. Already there is some vulnerability posted for persistenceservice service of java web start. But in Basicservice also we can run any file on the client using showDocument method. Just give the URL of file on client computer. If the browser has software attached to run that filetype it will be run automatically without user knowledge.

-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of the Sun Java Runtime. User interaction is
required in that a target must visit a malicious web page or open a
malicious JNLP file.
The specific flaw exists within the code responsible for handling
Pack200 compressed JAR files. During decompression, several fields
within a Pack200 header are trusted and used to calculate sizes for heap
buffer allocations. By providing malicious values an attacker can create
