1. Impact

   A format string security vulnerability in the Sun Remote Services
   (SRS) Net Connect Software may allow an unprivileged local user to
   execute arbitrary code with root privileges.

   Sun acknowledges with thanks, Sean Larsson of iDefense Labs
   (http://www.idefense.com) for bringing this issue to our attention.

   This issue is also described in the following document:

   http://labs.idefense.com/intelligence/vulnerabilities/display.php?i
   d=610

2. Contributing Factors

   This issue can occur in the following releases:

   SPARC Platform
     * SRS Net Connect Software version 3.2.3 (for Solaris 8, 9 and 10)
       without patch 125713-02
     * SRS Net Connect Software version 3.2.4 (for Solaris 8, 9 and 10)
       without patch 123870-03

   Notes:

   1. The SRS Net Connect software only runs on the SPARC platform;
   therefore the x86 platform is not affected by this issue.

   2. This issue only occurs on systems which have installed the Sun
   Remote Services (SRS) Net Connect software. The SRS Net Connect
   software is not bundled with Solaris but is available for download at:

   https://srsnetconnect.sun.com/

   3. To determine the version of the SRS Net Connect software installed
   on the system, the filename of the SRS Net Connect Uninstall script
   can be examined by running the following command:
    $ ls -l /opt/SUNWsrspx/bin/Uninstall*
    -r-xr-----   1 root   root  6422 Mar 16 19:34
    /opt/SUNWsrspx/bin/UninstallNetConnect.003.002.004.sh

   The example above shows SRS Net Connect version 3.2.4 is installed on
   the system.

3. Symptoms

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

4. Relief/Workaround

   There is no workaround for this issue. Please see the Resolution
   section below.

5. Resolution

   This issue is addressed in the following releases:

   SPARC Platform

       with patch 125713-02 or later
     * SRS Net Connect Software version 3.2.4 (for Solaris 8, 9 and 10)
