Update of the modules for security issues ESX service console

Today, I was asked a question on the vervsion of OpenSSH used on the service console for our environment vSphere 4.0. Apparently, there is a vulnerability in OpenSSH 5.6/7 with a certificate which has been corrected in version 5.8. My response to the security team has been we are the 4.3.p2 and as a result, this issue does not concern us. So the following questions then becomes why you are not in the latest version?

I'm curious to know if someone has already discussed with VMware on these types of security issues where the components used by RHEL, like OpenSSH, are vulnerable. What was their response to attempts to update this kind of things? I guess some of the answers would not be supported, you'll break, if you patch it's no guarantee your fix will not get downgraded, etc..

I'm looking for is a solid answer that explains why we do not have that kind of stuff to ESX, only when VMware provides the fix. I could contact the support, but I thought her first check and see what others have met.

Thank you

Hello.

I think that all the reasons you mentioned (not supported, you're going to break, if you patch it's no guarantee your fix will not get downgraded, etc.) are pretty much true.  The ESX 4.1 Patch Management Guide stated in the FAQ section:

When a rpm on my ESX host has an equivalent Linux, can I use the Linux RPM to upgrade my system?
N ° VMware recommends that you update your host ESX 4.1 with RPM provided by VMware.

An answer I could use would be to take a step back to look at the bigger picture.  Is a SSH, which should be secluded/protected to some extent in a first time, have a vulnerability more risky than having an ESX host unstable/not supported with X number of VMS running on it.

Good luck!

  • Satellite A200-1DN - the update of the BIOS for Windows 7

    I am running 32-bit Windows 7 on a Satellite A200 1DN. I had battery problems (plugged in, does not support) and I understand that I have to update my BIOS. However I can't find an update of the BIOS for Windows 7, only Vista and XP.

    Can anyone help? I should update with the BIOS in Vista? Are there other options to fix this battery? I already tried an ATX reset and uninstall method battery Microsoft ACPI compatible controls.

    Any advice would be much appreciated.

    Thank you
    Ian

    Theoretically, you can install Windows Vista to update Bios and return Win 7, then. Before you do, try this:

    Unplug the computer from the power adapter and turn it on. Let the computer battery power until the computer turns off
    Remove the battery. Using a soft cloth, wipe the battery packs connectors and AC adapters.
    Reinsert the battery and plug it into the power adapter

    also, have you had the same problem before installing Win 7?

  • Script to change the settings for security vSwith

    We need a script to change the settings for security vSwitch.

    To change the below: -.

    Mac changes Accept Reject

    Forged pass Accept Reject

    The two parameters above must change on all the vSwitch in vcenter.

    Altogether. Pass an argument to Get-VMHost

    If you pass the complete hostname (as he shows in vCenter), it will act on the single host:

    Get-VMHost MYESXi01.mydomain.com

    or if you want to do more, you can pass a joker:

    Get-VMHost MYESXi*.mydomain .com

    FWIW, I think that should do the same thing on a single line, if you like this better

    Get-VMhost|%{$hv=Get-View $_.ID;$ns=$hv.ConfigManager.NetworkSystem;($hv.Config.Network.Vswitch)|%{$vs=$_.Spec;$vs.Policy.Security.AllowPromiscuous=$false;$vs.Policy.Security.ForgedTransmits=$false; $vs.Policy.Security.MacChanges=$false;$ns.UpdateVirtualSwitch($_.Name,$vs)}}

  • The new update with the Patch for Camera Raw does not work. Code U44M1P34

    Hello

    I have a problem with the new CC update - including the patch for Camera Raw 8.7.1

    Error code: U44M1P34

    Photoshop CC (2014)

    After Effects CC (2014)

    Brisge CC

    The log file shows 1 fatal error:

    FATAL: Payload ' Photoshop Camera Raw 8_8.7_AdobeCameraRaw8.0All 8.0.0.22 with a number that follows.

    I tried to uninstall reinstall. Did not work at all, because the same problem appears.

    I have not installed in other folders. All other updates worked - but not this update. The problem seems to bee only caused by the Camera Raw update.

    Are there other people with the same problem? Any ideas?

    Thanks in advance and greetings,

    Now, the programs are on the actual status with all the updates that are included and everythings looks fine.

  • After that I changed the Duplex parameter on NIC's Service console, I am not able to connect the ESX host

    Hi all

    Please help solve my problem.

    After that I changed the Duplex parameter on NIC's Service console, I am unable to connect the ESX host. How can I reset the 100 MB NETWORK card duplex. Can someone help me please.

    Concerning

    Vijay

    Hello

    As the bulb you have two problems that are not related.

    (1) duplex setting, your switch and NIC must match. If one is assigned to auto-negotiation, then the other must be set to auto-negotiation. Personally, I tend to let auto-negotiation unless there is an absolute reason to spend. If you then turn on the both sides of the interface, the switch port and esxcfg-NICS allows you to change the duplex, etc.

    (2) passwords for root are not related to the network unless you have also run esxcfg-auth authentication remote.  The only time I saw what you have here is when the system is configured to try to authenticate remote and not locally.

    The two problems are fixable by booting into single-user mode, set the duplex and reset the password.

    How to clear VMFS in the ESX service console?

    Post's er has hinted at it earlier.  To remove a vmfs, use fdisk, and then delete the partition.  Then run esxcfg-rescan vmhba < 0 | 1. 2 >

    This removes the vmfs and make sure that it does not appear on a new analysis.

  • The update of the BIOS for Satellite Pro M70 does support TPM?

    Hello

    There was an update of the bios that is specially designed for Vista... = bios-vista - 510win.zip on the Toshiba site...

    Although my Satellite Pro M70-113 did not support the default TPM module (BIOS verson 1.1, I always have this), is it possible that this update includes the TPM secure to enable bitlocker on vista?

    Can someone check and confirm please... :)

    And secondly, is configuration BIOS update for Windows utility saves the current state of the BIOS in some external as backup media, while if it happens with the process of update... the previous version can be restored in return?

    And a BIOS may be downgraded?

    Thank you.

    Hello

    (1.) I m not 100% sure but I think the new BIOS for the M70 does not support the TPM secure. I read somewhere that all BIOS versions that support TPM on Toshiba laptops cannot be updated by a common user, but the user must contact the authorized Toshiba service provider for these updates.
    That's why I think that Toshiba would not any BIOPS version by download issue if this BIOS would support the TPM.

    2.) now something about the second question:
    The new BIOS version replaces the old BIOS and BIOS States and to my knowledge it of not possible to save the settings for a backup more later.
    Generally, you must be careful with any update of the BIOS. Bad BIOS or bad update procedure may damage the jury!

  • Cannot install the fix for security for Windows 8 (KB2909210)

    I tried dozens of times to install the latest updates of Windows 8 to my computer and nothing works. My computer refuses to install with the Windows automatic update. Whenever I try, I get a message that says no: 'No update available,' with a bar of green on the side, as if everything is OK.
    THEN, the Windows Update window updates and even once, I get a yellow shield, exclamation mark in the middle and a message that says I still have 38 updates important to install and 2 in option.

    So I decide that very well, since it refuses to work, why not go to the Download Center and try to install each patch or update individually and manually. For example, I went to the download page manual for upgrading security in the title of this message, KB2909210 - http://www.microsoft.com/en-us/download/details.aspx?id=41800. I select English and click on 'Download' and following the instructions. A new window opens (I use Firefox) and it asks me if I want to open the file with the stand-alone Installer Windows Update (default) or save the file. If I choose to open the file directly from this point or save it first and then open it with the WUSI, I receive a new message, the red giant 'X' well displayed prominently, which says "Windows Update Standalone Installer" in large blue text below, "the update is not applicable to your computer."

    POPPYCOCK! This specific update was listed when I tried to use the automatic feature of Windows Update in Control Panel. As I said earlier, I tried several times to install it in this way, but he refused to install. Also fails the manual route through the Download Center. Apparently, there are updates of security to 2012 (!) who do not and will not be installed.

    Help! I already did a restore of the system more than a month after my hard drive has been corrupted. I made then a system reset to start over with what I thought would be a totally clean machine. Now, it seems that my hard disk is permanently damaged. Therefore, Windows refuses to properly update and patch up many vulnerabilities and security flaws. I'm tired of this. Help me to redo my computer safe and trustworthy!

    Windows Update corruption errors prevent Windows to install updates and service packs.

    To resolve this problem, use Deployment Image Servicing and Management (DISM) Inbox. Then, install the update or Windows service pack again.

    1. Open an elevated command prompt. To do this, enter in the right edge of the screen, and then click Search. Or, if you use a mouse, point to the corner bottom right of the screen, then click on Search. Type the command prompt in the Search box, right click invite, and then click run as administrator. If you are prompted for an administrator password or a confirmation, type the password, or click allow.
    2. Type the following commands. Press ENTER after each command.

    Note It may take a few minutes for each operation in order to fill.

    • DISM.exe / Online/Cleanup-image /Scanhealth
    • DISM.exe / Online/Cleanup-image /Restorehealth
  • Close the command prompt, and then run Windows Update again.
  • DISM creates a log (% windir%/Logs/CBS/CBS.log) file that captures any issues that the tool found or fixed. %windir%\System32 is the folder in which Windows is installed. For example, the %windir%\System32 folder is C:\Windows.
