docId=hpuxSecurityMatrix
Or via anonymous ftp:
ftp://ftp.itrc.hp.com/export/patches/hp-ux_patch_matrix/
The HP-UX Security Patch Matrix, updated daily, categorizes
security patches by platform/OS release, and by Bulletin topic.
The Security Patch Check tool completely automates the process of
reviewing the Security Patch Matrix for HP-UX 11.XX Versions.
NOTE: Installing patches listed in the Security Patch Matrix will
completely implement the RESOLUTION in the Security Bulletin
_only_ if there are no MANUAL ACTIONS included.
The Security Patch Check tool can also verify that a Security
Bulletin RESOLUTION has been implemented on HP-UX 11.XX Versions
provided that no MANUAL ACTIONS were included. The Security Patch
Check tool cannot verify patches implemented via product upgrade.
