CHANGE SUMMARY: Rev. 01 Added HP-UX B.11.04 (VVOS) patches
-----------------------------------------------------------------
**REVISED 01**
A. Background
Many system modules create insecure temporary files with a
name based on a process id, and write subsequent input
to that file. Improper error checking of various sytem
calls results in a vulnerability.
