     * Synopsis: Security Vulnerability in Processing XSLT Stylesheets
       Affects Sun Java System Application Server and Web Server
     * Category: Security
     * Product: Sun Java System Application Server Standard Edition 8.2,
       Sun Java System Application Server Enterprise Edition 8.2, Sun
       Java System Application Server PE 9 , Sun Java System Web Server
       7.0
     * BugIDs: 6542007, 6523817

1. Impact

   Certain releases of Sun Java System Application Server and Sun Java
   System Web Server (listed in "Contributing Factors") do not securely
   process XSLT stylesheets contained in XSLT Transforms in XML
   Signatures. This could allow malicious XLST stylesheets to be executed
   which may, for example, allow execution of an arbitrary Java method.

   Sun acknowledges, with thanks, Brad Hill of iSEC Partners, for
   bringing this issue to our attention.

2. Contributing Factors

   This issue can occur in the following releases:

   SPARC Platform
     * Sun Java System Web Server 7.0 without Update 1
     * Sun Java System Application Server Platform Edition 8.2 without
       file-based patch 124679-01 or SVR4 patch 124672-02
     * Sun Java System Application Server Enterprise Edition 8.2 without
       file-based patch 124675-01 or SVR4 patch 124672-02
     * Sun Java System Application Server Platform Edition 9.0

   x86 Platform
     * Sun Java System Web Server 7.0 without Update 1
     * Sun Java System Application Server Platform Edition 8.2 without
       file-based patch 124680-01 or SVR4 patch 124673-02
     * Sun Java System Application Server Enterprise Edition 8.2 without
       file-based patch 124676-01 or SVR4 patch 124673-02
     * Sun Java System Application Server Platform Edition 9.0

   Linux
     * Sun Java System Web Server 7.0 without Update 1
     * Sun Java System Application Server Platform Edition 8.2 without
       file-based patch 124681-01 or RHEL3.0/RHEL4.0 (Pkg_patch)
       124674-02
     * Sun Java System Application Server Enterprise Edition 8.2 without
       file-based patch 124677-01 or RHEL3.0/RHEL4.0 (Pkg_patch)
       124674-02
     * Sun Java System Application Server Platform Edition 9.0

   Windows
     * Sun Java System Web Server 7.0 without Update 1
     * Sun Java System Application Server Platform Edition 8.2 without
       file-based patch 124682-01
     * Sun Java System Application Server Enterprise Edition 8.2 without
       file-based patch 124678-01 or package-based patch
       124684-02
     * Sun Java System Application Server Platform Edition 9.0

   HP-UX
     * Sun Java System Web Server 7.0 without Update 1

   Note: No other versions of the applications listed above are
   vulnerable to this issue.

   To determine the version of Sun Java System Application server on a
   system, the following command can be run:
    $ <AS_INSTALL>/bin/asadmin version --verbose

   (Where <AS_INSTALL> is the installation directory of the Application
   Server).

   To determine the version of Sun Java System Web Server on a system,
   the following command can be run:
    $ <WS-install>/https-<host>/start -version

   (Where <WS-install> is the installation directory of the Web Server
   and <host> should be the actual host name on which the Web Server is
   installed).

   Note: Bug 6523817 only impacts Sun Java System Web Server, and bug
   6542007 impacts Sun Java System Application Server.

3. Symptoms

   There are no predictable symptoms that would indicate the described
   issue has been exploited.
