Filed under
HowTos

This short article explains how you can move/convert a Xen guest that uses disk images to LVM volumes. Virtual machines that use disk images are very slow and heavy on disk IO, therefore it is often better to use LVM.

Security Leftovers

  • efail: Outdated Crypto Standards are to blame
    I have a lot of thoughts about the recently published efail vulnerability, so I thought I'd start to writeup some of them. I'd like to skip all the public outrage about the disclosure process for now, as I mainly wanted to get into the technical issues, explain what I think went wrong and how things can become more secure in the future. I read lots of wrong statements that "it's only the mail clients" and the underlying crypto standards are fine, so I'll start by explaining why I believe the OpenPGP and S/MIME standards are broken and why we still see these kinds of bugs in 2018. I plan to do a second writeup that will be titled "efail: HTML mails are to blame". I assume most will have heard of efail by now, but the quick version is this: By combining a weakness in cryptographic modes along with HTML emails a team of researchers was able to figure out a variety of ways in which mail clients can be tricked into exfiltrating the content of encrypted e-mails. Not all of the attack scenarios involve crypto, but those that do exploit a property of encryption modes that is called malleability. It means that under certain circumstances you can do controlled changes of the content of an encrypted message. [...] Properly using authenticated encryption modes can prevent a lot of problems. It's been a known issue in OpenPGP, but until know it wasn't pressing enough to fix it. The good news is that with minor modifications OpenPGP can still be used safely. And having a future OpenPGP standard with proper authenticated encryption is definitely possible. For S/MIME the situation is much more dire and it's probably best to just give up on it. It was never a good idea in the first place to have competing standards for e-mail encryption. For other crypto protocols there's a lesson to be learned as well: Stop using unauthenticated encryption modes. If anything efail should make that abundantly clear.

    A Comcast Xfinity website was leaking Wi-Fi names and passwords, meaning now is a good time to change your Wi-Fi passcode. The site, intended to help new customers set up new routers, could easily be fooled into revealing the location of and password for any customer’s Wi-Fi network. A customer ID and a house or apartment number was all would-be attackers needed to get full access to your network, along with your full address.

  • “Ultimate Private Cloud” Demo, Under The Hood!
    At the recent Red Hat Summit in San Francisco, and more recently the OpenStack Summit in Vancouver, the OpenStack engineering team worked on some interesting demos for the keynote talks. I’ve been directly involved with the deployment of Red Hat OpenShift Platform on bare metal using the Red Hat OpenStack Platform director deployment/management tool, integrated with openshift-ansible. I’ll give some details of this demo, the upstream TripleO features related to this work, and insight around the potential use-cases.

    Juniper Networks and Red Hat have tightened their integration efforts in a move to help ease enterprise adoption of cloud-native platforms and bolster their own offerings against the likes of VMware and Cisco. The latest platform integration includes the Red Hat OpenStack Platform; Red Hat’s OpenShift Container Platform running as a platform-as-a-service (PaaS) on top of or next to the OpenStack platform depending on deployment architecture; and Juniper’s Contrail Enterprise Multi-Cloud platform running as the networking and security layer to unify those together. This integration is designed as a managed system to help deploy and run applications and services on any virtual machine (VM), container platform, and any cloud environment.
