===============================================================================
                            VULNERABILITY SUMMARY

VULNERABILITY: Return only new keys in randkey

PLATFORMS: AIX 5.3, 6.1 and 7.1
           VIOS 2.X

SOLUTION: Apply the fix as described below.

THREAT: See below

CVE Numbers: CVE-2014-5351

Reboot required? NO

Workarounds? NO

Protected by FPM? NO

Protected by SED? NO

===============================================================================

                           DETAILED INFORMATION

I. DESCRIPTION

    CVE-2014-5351

    kadmind sends old keys in a response to a -randkey -keepold request, which

allows

    remote authenticated users to forge tickets by leveraging administrative

access.

II. CVSS

    CVE-2014-5351

    CVSS Base Score:4

    CVSS Temporal Score:see http://xforce.iss.net/xforce/xfdb/97028

    CVSS Environmental Score*:Undefined

    CVSS Vector: (AV:N/AC:L/Au:S/C:N/I:P/A:N)

III. PLATFORM VULNERABILITY ASSESSMENT

    To determine if your system is vulnerable, execute the following

    command to obtain the NAS fileset level:

        lslpp -L krb5.client.rte

    	lslpp -L krb5.server.rte

    The following fileset levels are vulnerable:

    AIX 7.1, 6.1, 5.3: all NAS versions below 1.5.0.7 and 1.6.0.2

    VIOS 2.X: all NAS versions below 1.5.0.7 and 1.6.0.2

    Note:

    - NAS 1.6.0.x is a separate release branch for NAS SPNEGO feature.

    - To find out whether the affected filesets are installed on your

      systems, refer to the lslpp command found in AIX user's guide.

IV. FIXES

    A fix is available, and it can be downloaded from:

    https://www14.software.ibm.com/webapp/iwm/web/preLogin.do?source=aixbp

    If NAS SPNEGO feature is under use, then download NAS 1.6.0.2 version,

    else download NAS 1.5.0.7 version.

    To extract the fixes from the tar file:

    zcat NAS_1.X.0.X_aix_image.tar.Z | tar xvf -

    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 the fix installation:

    installp -apYd . krb5

    To install the fix package:

    installp -aXYd . krb5

V. WORKAROUNDS

    No workarounds.

        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.

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 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; thus, IBM does not warrant the fully

        correct functionality of an interim fix.

        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.

        To list all installed Interim Fixes:

        emgr -l

        To remove an installed Interim Fix:

        emgr -r -L ipkg_label # where ipgk_label is the label (e.g.,

                                     # IV61313s9a) of the interim fix

                                     # package being removed.
