REMEDIATION:

    A. FIXES

        IBM strongly recommends addressing the vulnerability now.

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

        ftp://aix.software.ibm.com/aix/efixes/security/java_jun2022_fix.tar
        http://aix.software.ibm.com/aix/efixes/security/java_jun2022_fix.tar
        https://aix.software.ibm.com/aix/efixes/security/java_jun2022_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_7.0.0.710.tar.gz   key_w_fix
        7.0.0      java7_64_installp_7.0.0.710.tar.gz   key_w_fix
        7.1.0      java7r1_32_installp_7.1.0.510.tar.gz key_w_fix
        7.1.0      java7r1_64_installp_7.1.0.510.tar.gz key_w_fix
        8.0.0      java8_32_installp_8.0.0.710.tar.gz   key_w_fix
        8.0.0      java8_64_installp_8.0.0.710.tar.gz   key_w_fix

        To extract the fixes from the tar file:

        tar xvf java_jun2022_fix.tar
        cd java_jun2022_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
        -----------------------------------------------------------------------------------------------------------------

        782cc8b09a11d0f7fe2aded7dee233396666e8416b5356bd731db5e6316078cf  java7r1_32_installp_7.1.0.510.tar.gz key_w_csum
        b39ec9b7d6cc88119cc746ac2c3d353f2cf11a8e6365601a9f985bfdf5f4ca3b  java7r1_64_installp_7.1.0.510.tar.gz key_w_csum
        a2f879d6eb074f9b0383847682c9f5d6ed98245654b0eb09206f414fcfa52f89  java8_32_installp_8.0.0.710.tar.gz   key_w_csum
        851ee51bb6f6be95da206116b73afe92cabcb302f034e0cc3bcd8d428f84928d  java8_64_installp_8.0.0.710.tar.gz   key_w_csum

        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]

        https://aix.software.ibm.com/aix/efixes/security/java_jun2022_advisory.asc.sig
        ftp://aix.software.ibm.com/aix/efixes/security/java_jun2022_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.
