    I received this security bulletin:  https://www.ibm.com/support/pages/node/7028209?myns=swgother&mynp=OCSSOQ2E&mync=E&cm_sp=swgother-_-OCSSOQ2E-_-E

    I am running the following on my HMC:
    Version: 10
    Release: 2
    Service Pack: 1031
    Build Level: 2304040146
    virtual X86

    The letter mentions affected versions were V10.1.1010.0  and V10.2.1030.0, but the fixes listed were for: V10.2.1040.0 and V10.1.1020.0.  To me, this is very confusing.

    I ran my configuration through FLRT at https://esupport.ibm.com/customercare/flrt/power and it replied:
    Input: HMC V10 R2 M1031
    Available Fixes: vMF70889

    Hi Robert

    It is really straight forward, you are running HMC V10R2 with service pack M1031.

    M1040 is just another service pack for your V10R2 HMC. If you look at fixcentral there is even a M1041 service pack available.

    But remember to always read the readme for the service pack/fix, before installing it.

    One significant security enhancement/change in M1040 is that unsecure telnet port 2300 is disabled on the HMC.  All IBM i remote console sessions now require a TLS connection!

    So, does MF71190 upgrade one to V10.2.1040.0, or is it applied to V10.2.1040.0?  If MF71190 is applied to V10.2.1040.0, then what does one apply to V10.2.1031 to address these CVE's?

    Hi Robert

    Sorry, if I wasn't specific enough.

    You need to apply the M1041 service pack (PTF MF71190) to you vHMC running V10R2M1031 to address and remediate these CVE's.

    Its a one-step service pack apply.
