   Solution Type: Sun Alert

   Solution  255608 :   A Security Vulnerability in OpenSolaris may Allow
   a Privileged User Inside a non-global Zone to Execute Arbitrary Code
   Within a Global Zone   
       
   Bug ID: 6756058

   Product
   OpenSolaris

   Date of Resolved Release: 26-Mar-2009

   SA Document Body
   A security vulnerability in OpenSolaris may allow a privileged user inside 
   a non-global zone to execute arbitrary code within a global zone:

   1. Impact

   Local privileged users inside a non-global zone may be able to execute
   arbitrary code within a global zone if an mdb process within the
   global zone attaches to a non-global zone process. The code would be
   executed with the privileges of the user running mdb, which could
   potentially be root.

   2. Contributing Factors

   This issue can occur in the following releases:
   SPARC Platform
     * OpenSolaris based upon builds snv_100 through snv_101

   x86 Platform
     * OpenSolaris based upon builds snv_100 through snv_101

   Note 1: Solaris 8, 9 and 10 are not impacted by this issue.
   Note 2: OpenSolaris distributions may include additional bug fixes
   above and beyond the build from which it was derived.  To determine
   the base build of OpenSolaris, the following command can be used:
    $ uname -v
    snv_86

   3. Symptoms

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

   4. Workaround

   To avoid this issue, do not use mdb from the global zone to debug
   processes in the non-global zone.

   5. Resolution

   This issue is addressed in the following releases:
   SPARC Platform
     * OpenSolaris based upon builds snv_102 or later

   x86 Platform
     * OpenSolaris based upon builds snv_102 or later
