Stack-based buffer overflow in javaws.exe in Sun Java Web Start in JRE 5.0 Update 11 and earlier, and 6.0 Update 1 and earlier, allows remote attackers to execute arbitrary code via a long codebase attribute in a JNLP file.

The Java Web Start utility distributed with the version of Sun Java Runtime Environment (JRE) installed on the remote host may be affected by a buffer overflow vulnerability. If an attacker can convince a user on the affected host to open a specially crafted JNLP file, it may be possible to execute arbitrary code subject to the user's privileges.

Updated java-1.5.0-sun packages that correct several security issues are available for Red Hat Enterprise Linux 4 Extras.

This update has been rated as having critical security impact by the Red Hat Security Response Team.

The Java Runtime Environment (JRE) contains the software and tools that users need to run applets and applications written using the Java programming language.

The Javadoc tool was able to generate HTML documentation pages that contained cross-site scripting (XSS) vulnerabilities. A remote attacker could use this to inject arbitrary web script or HTML.
(CVE-2007-3503)

The Java Web Start URL parsing component contained a buffer overflow vulnerability within the parsing code for JNLP files. A remote attacker could create a malicious JNLP file that could trigger this flaw and execute arbitrary code when opened. (CVE-2007-3655)

The JSSE component did not correctly process SSL/TLS handshake requests. A remote attacker who is able to connect to a JSSE-based service could trigger this flaw leading to a denial-of-service.
(CVE-2007-3698)

A flaw was found in the applet class loader. An untrusted applet could use this flaw to circumvent network access restrictions, possibly connecting to services hosted on the machine that executed the applet.
(CVE-2007-3922)

All users of java-sun-1.5.0 should upgrade to these packages, which contain Sun Java 1.5.0 Update 12 that corrects these issues.

NOTE: This combination of rpm's replaces j2sdk-1.4.2 with jdk-1.5.0.
So your java will change from version 1.4.2 to 1.5.0. We apologize if this causes any problems, but it needed to be done for security reasons.

A flaw in the applet caching mechanism of the Java Runtime Environment (JRE) did not correctly process the creation of network connections. A remote attacker could use this flaw to create connections to services on machines other than the one that the applet was downloaded from.
(CVE-2007-5232)

Multiple vulnerabilities existed in Java Web Start allowing an untrusted application to determine the location of the Java Web Start cache. (CVE-2007-5238)

Untrusted Java Web Start Applications or Java Applets were able to drag and drop a file to a Desktop Application. A user-assisted remote attacker could use this flaw to move or copy arbitrary files.
(CVE-2007-5239)

The Java Runtime Environment (JRE) allowed untrusted Java Applets or applications to display oversized Windows. This could be used by remote attackers to hide security warning banners. (CVE-2007-5240)

Unsigned Java Applets communicating via a HTTP proxy could allow a remote attacker to violate the Java security model. A cached, malicious Applet could create network connections to services on other machines. (CVE-2007-5273)

Unsigned Applets loaded with Mozilla Firefox or Opera browsers allowed remote attackers to violate the Java security model. A cached, malicious Applet could create network connections to services on other machines. (CVE-2007-5274) The Javadoc tool was able to generate HTML documentation pages that contained cross-site scripting (XSS) vulnerabilities.

The remote host is affected by the vulnerability described in GLSA-200804-20 (Sun JDK/JRE: Multiple vulnerabilities)

    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.
    The Zero Day Initiative, TippingPoint and John Heasman reported     multiple buffer overflows and unspecified vulnerabilities in Java Web     Start (CVE-2008-1188, CVE-2008-1189, CVE-2008-1190,     CVE-2008-1191).
    Hisashi Kojima of Fujitsu and JPCERT/CC reported a security issue     when performing XSLT transformations (CVE-2008-1187).
    CERT/CC reported a Stack-based buffer overflow in Java Web Start     when using JNLP files (CVE-2008-1196).
    Azul Systems reported an unspecified vulnerability that allows     applets to escalate their privileges (CVE-2007-5689).
    Billy Rios, Dan Boneh, Collin Jackson, Adam Barth, Andrew Bortz,     Weidong Shao, and David Byrne discovered multiple instances where Java     applets or JavaScript programs run within browsers do not pin DNS     hostnames to a single IP address, allowing for DNS rebinding attacks     (CVE-2007-5232, CVE-2007-5273, CVE-2007-5274).
    Peter Csepely reported that Java Web Start does not properly     enforce access restrictions for untrusted applications (CVE-2007-5237,     CVE-2007-5238).
    Java Web Start does not properly enforce access restrictions for     untrusted Java applications and applets, when handling drag-and-drop     operations (CVE-2007-5239).
    Giorgio Maone discovered that warnings for untrusted code can be     hidden under applications' windows (CVE-2007-5240).

    Multiple unspecified vulnerabilities might allow for escalation of     privileges (CVE-2008-0657).
  Impact :

    A remote attacker could entice a user to run a specially crafted applet     on a website or start an application in Java Web Start to execute     arbitrary code outside of the Java sandbox and of the Java security     restrictions with the privileges of the user running Java. The attacker     could also obtain sensitive information, create, modify, rename and     read local files, execute local applications, establish connections in     the local network, bypass the same origin policy, and cause a Denial of     Service via multiple vectors.
  Workaround :

    There is no known workaround at this time.

The remote Mac OS X 10.4 host is running a version of Java for Mac OS X that is older than release 6.

The remote version of this software contains several security vulnerabilities that may allow a rogue Java applet to escalate its privileges and to add or remove arbitrary items from the user's KeyChain.

To exploit these flaws, an attacker would need to lure an attacker into executing a rogue Java applet.

The IBM Java JRE/SDK has been brought to release 1.5.0 SR5a, containing several bugfixes, including the following security fixes :

  - A buffer overflow vulnerability in the image parsing     code in the Java(TM) Runtime Environment may allow an     untrusted applet or application to elevate its     privileges. For example, an applet may grant itself     permissions to read and write local files or execute     local applications that are accessible to the user     running the untrusted applet. (CVE-2007-2788 /     CVE-2007-2789 / CVE-2007-3004 / CVE-2007-3005)

    A second vulnerability may allow an untrusted applet or     application to cause the Java Virtual Machine to hang.

  - A buffer overflow vulnerability in the Java Web Start     URL parsing code may allow an untrusted application to     elevate its privileges. For example, an application may     grant itself permissions to read and write local files     or execute local applications with the privileges of the     user running the Java Web Start application.
    (CVE-2007-3655)

  - A security vulnerability in the Java Runtime Environment     Applet Class Loader may allow an untrusted applet that     is loaded from a remote system to circumvent network     access restrictions and establish socket connections to     certain services running on the local host, as if it     were loaded from the system that the applet is running     on. This may allow the untrusted remote applet the     ability to exploit any security vulnerabilities existing     in the services it has connected to. (CVE-2007-3922)

    (CVE-2007-3655)

  - A security vulnerability in the Java Runtime Environment     Applet Class Loader may allow an untrusted applet that     is loaded from a remote system to circumvent network     access restrictions and establish socket connections to     certain services running on the local host, as if it     were loaded from the system that the applet is running     on. This may allow the untrusted remote applet the     ability to exploit any security vulnerabilities existing     in the services it has connected to. (CVE-2007-3922)
