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.
