1. Impact

   A local unprivileged user may be able to gain unauthorized root
   privileges due to a security vulnerability in libraries associated
   with the PGX32 Frame Buffer.
   
2. Contributing Factors

   This issue can occur in the following releases:
   
   SPARC Platform
     * Solaris 2.5.1 without patches 107714-25 and 107851-25
     * Solaris 2.6 without patches 107715-25 and 107851-25
     * Solaris 7 without patches 107716-26 and 107851-25
     * Solaris 8 without patch 109154-20
     * Solaris 9 without patch 112601-09
       
   Note: Solaris on the x86 platform is not affected.
   
   This issue only occurs when a PGX32 frame buffer is installed. To
   verify if a Sun system is equipped with a PGX32 frame buffer, use the
   "/usr/platform/`uname -m`/sbin/prtdiag" command. An output line
   containing "TSI,gfxp" in the "Name" column indicates that a PGX32
   frame buffer is installed.
   
3. Symptoms

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