1. Impact

   A local unprivileged user may be able to gain additional access
   privileges to VERITAS File System (VxFS) files due to incorrect
   permissions being set when Access Control Lists (ACLs) are being
   utilized.

     * VxFS 3.4 (for Solaris 2.6) without patch 110433-08
     * VxFS 3.4 (for Solaris 7) without patch 110434-09
     * VxFS 3.4 (for Solaris 8) without patch 110435-08

     * VxFS 3.5 (for Solaris 8) without patch 113206-05

   VERITAS incident #113367.
   
3. Symptoms

   The ACL permissions are not set consistently when new files are
   created. The result is that the permissions for some new files may be
   more open than intended.
