   SA Document Body
Vulnerability in Solaris 10 Trusted Extensions (see details below)

1. Impact

   A security vulnerability in Solaris 10 Trusted Extensions labeled
   networking may allow untrusted applications in separate labeled zones
   to exchange data on the local system by circumventing label
   restrictions.

2. Contributing Factors

   This issue can occur on the following releases:
   SPARC Platform
     * Solaris 10 without patch 127127-11

   x86 Platform
     * Solaris 10 without patch 127128-11

   Note 1: Solaris 8 and Solaris 9 are not impacted by this issue.
   Note 2: This issue only impacts Solaris 10 systems which have
   installed and configured Solaris Trusted Extensions. Solaris Trusted
   Extensions is available starting in the Solaris 10 11/06 release.
   To determine if a system is configured with Trusted Extensions, the
   following command can be run:
       $ svcs labeld
       STATE          STIME    FMRI
       online         16:19:20 svc:/system/labeld:default
   If the system is configured with Trusted Extensions, the "labeld"
   service will have an instance in the online state.

3. Symptoms

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

4. Workaround

   Interim Security Relief (ISR) is available for the following releases
   from http://sunsolve.sun.com/tpatches
   Some customers may be restricted to running the Common Criteria
   evaluated version of the Solaris Trusted Extensions OE.  These
   customers may use the following IDRs that have been created based on
   the estimate that Kernel Update patches 125100-08 (SPARC) and
   125101-08 (x86) will be the Target Of Evaluation (TOE):
   SPARC Platform
     * Solaris 10  IDR137431-01

   x86 Platform
     * Solaris 10 IDR137432-01

   Note: This document refers to one or more temporary patches
   (T-Patches) and/or Interim Security Relief (IDRs) which are designed
   to address the concerns identified herein. Sun has limited experience
   with these T-Patches and IDRs due to their interim nature. As such,
   you should only install the T-Patches or IDRs on systems meeting the
   configurations described above. Sun may release full patches at a
   later date, however, Sun is under no obligation whatsoever to create,
   release, or distribute any such patch.

5. Resolution

   This issue is addressed in the following releases:
   SPARC Platform
     * Solaris 10 with patch 127127-11 or later

   x86 Platform
     * Solaris 10 with patch 127128-11 or later
