and by bulletin topic. Security Patch Check completely
automates the process of reviewing the patch matrix for
11.XX systems. Please note that installing the patches
listed in the Security Patch Matrix will completely
implement a security bulletin _only_ if the MANUAL ACTIONS
field specifies "No."
The Security Patch Check tool can verify that a security
bulletin has been implemented on HP-UX 11.XX systems providing
that the fix is completely implemented in a patch with no
manual actions required. The Security Patch Check tool cannot
verify fixes implemented via a product upgrade.
For information on the Security Patch Check tool, see:
