The fixes can be downloaded via ftp         from:          ftp://aix.software.ibm.com/aix/efixes/security/infiniband_fix.tar          The link above is to a tar file containing this signed         advisory, fix packages, and PGP signatures for each package.         The fixes below include prerequisite checking. This will         enforce the correct mapping between the fixes and AIX         Technology Levels.

For example:          csum -h SHA1 -i Advisory.asc         sha1sum -c Advisory.asc          These sums should match exactly. The PGP signatures in the tar         file and on this advisory can also be used to verify the         integrity of the fixes.  If the sums or signatures cannot be         confirmed, contact IBM AIX Security at         security-alert@austin.ibm.com and describe the discrepancy.       C. FIX AND INTERIM FIX INSTALLATION          IMPORTANT: If possible, it is recommended that a mksysb backup         of the system be created.  Verify it is both bootable and         readable before proceeding.          To preview a fix installation:          installp -a -d fix_name -p all  # where fix_name is the name of the                                         # fix package being previewed.         To install a fix package:          installp -a -d fix_name -X all  # where fix_name is the name of the                                         # fix package being installed.          Interim fixes have had limited functional and regression         testing but not the full regression testing that takes place         for Service Packs; however, IBM does fully support them.          Interim fix management documentation can be found at:          http://www14.software.ibm.com/webapp/set2/sas/f/aix.efixmgmt/home.html          To preview an interim fix installation:          emgr -e ipkg_name -p         # where ipkg_name is the name of the                                      # interim fix package being previewed.          To install an interim fix package:          emgr -e ipkg_name -X         # where ipkg_name is the name of the                                      # interim fix package being installed.  V. WORKAROUNDS       Select one of the following:    ----------------------------      1) Enabling PowerSC with DoD.xml profile will prevent this vulnerability.      2) Running aixpert with high-level security options (aixpert -l high)      3) Running aixpert with medium-level security options (aixpert -l medium)      4) Invoking fpm -l high to remove setuid and setgid permissions for high        level security.      5) Invoking fpm -l medium to remove setuid and setgid permissions that        fall into medium level security.  VI. OBTAINING FIXES      AIX security fixes can be downloaded from:          ftp://aix.software.ibm.com/aix/efixes/security      AIX fixes can be downloaded from:          http://www.ibm.com/eserver/support/fixes/fixcentral/main/pseries/aix      NOTE: Affected customers are urged to upgrade to the latest     applicable Technology Level and Service Pack.
