REMEDIATION:

    A. FIXES

        AIX and VIOS fixes are available.


        The AIX and VIOS fixes can be downloaded via ftp or http from:

        ftp://aix.software.ibm.com/aix/efixes/security/java_feb2022_fix.tar
        http://aix.software.ibm.com/aix/efixes/security/java_feb2022_fix.tar
        https://aix.software.ibm.com/aix/efixes/security/java_feb2022_fix.tar 

        The link above is to a tar file containing this signed
        advisory, fix packages, and OpenSSL signatures for each package.
        The fixes below include prerequisite checking. This will
        enforce the correct mapping between the fixes and AIX
        Technology Levels.

        Java       Fix (*.Z)                            KEY
        ---------------------------------------------------------
        7.0.0      java7_32_installp_7.0.0.700.tar.gz   key_w_fix
        7.0.0      java7_64_installp_7.0.0.700.tar.gz   key_w_fix
        7.1.0      java7r1_32_installp_7.1.0.500.tar.gz key_w_fix
        7.1.0      java7r1_64_installp_7.1.0.500.tar.gz key_w_fix
        8.0.0      java8_32_installp_8.0.0.700.tar.gz   key_w_fix
        8.0.0      java8_64_installp_8.0.0.700.tar.gz   key_w_fix

        To extract the fixes from the tar file:

        tar xvf java_feb2022_fix.tar
        cd java_feb2022_fix

        Verify you have retrieved the fixes intact:

        The checksums below were generated using the
        "openssl dgst -sha256 [filename]" command as the following:

        openssl dgst -sha256                                              filename                             KEY

        These sums should match exactly. The OpenSSL 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 Support at
        http://ibm.com/support/ and describe the discrepancy.         

        openssl dgst -sha256 -verify [pubkey_file] -signature [advisory_file].sig [advisory_file]

        openssl dgst -sha256 -verify [pubkey_file] -signature [ifix_file].sig [ifix_file]

        ftp://aix.software.ibm.com/aix/efixes/security/java_feb2022_advisory.asc.sig

    B. FIX AND INTERIM FIX INSTALLATION

        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.

WORKAROUNDS AND MITIGATIONS:

None.
