The Security Patch Check tool cannot verify fixes implemented via a product upgrade. For information on the Security Patch Check tool, see: http://www.software.hp.com/cgi-bin/swdepot_parser.cgi/cgi/ displayProductInfo.pl?productNumber=B6834AA The security patch matrix is also available via anonymous ftp: ftp://ftp.itrc.hp.com/export/patches/hp-ux_patch_matrix/ On the "Support Information Digest Main" page: click on the "HP Security Bulletin Archive".
