    Comment #20503242

    Ignoring MD5/image format-specific collision realities, theoretically an attacker could submit a contraband image that collides with a valid, allowed image they may want to remove.…

    Not for me - seems it depends on libssl1.0 and buster ships 1.1

    It has good in-kernel support for virtio drivers (e.g. kvm, bhyve, vmware) and can also run domU in the latest release. It doesn't support "vmware tools" as such, but does support …

    Well, it's not obsolete - more incomplete. OpenBSD has supported ipv6 natively for a long, long time. Additionally, with a "home/office" router, there's many ways that IPv6 may be …

    Not 100% sure, but I think this is to mitigate exploitation of UAF (Use After Free) flaws. Adding an unpredictable delay in between when an application frees some memory, and it be…

    > anyone wanting to know OpenBSD's position on virtualization should spend 20m-1hr digging through threads like that Okay, okay. Personally, I think the fact that OpenBSD did not s…

    Comment #10617442

    If you actually read the thread he was reacting to the premise that: as a secure operating system, OpenBSD should implement virtualisation (in this case, Xen) due to its security b…

    Comment #10612663

    Is this really a compromise? OpenBSD has happily run as a guest for a long time now, with various virtio drivers being added some time ago. Solutions like virtualbox and xen reach …

    On the flip side, if they were offering TLS services to these sites, they're literally man-in-the-middling encrypted comms to those sites. And in scope of US law-enforcement/intel …

    Comment #10150165

    OpenBSD has had VirtIO (supported by KVM, VMWare and now virtualbox too) guest support for a while now. AWS uses Xen and domU support is a lot more invasive - OpenBSD had supported…

    Theo has been softening on x86 virt for a long time. Additionally, he's still right. Don't rely on it to enforce security boundries (e.g. host untrusted systems and trusted systems…

    I guess the goal of Security is to not become the next OPM or Hacking Team. I agree with what you say regarding perimeter security, a concept quickly decreasing in relevance in tod…

    I'm a security guy so I obviously have a differing viewpoint, but when it comes to ensuring what data comes in and leaves your environment there's little choice. The ability to ana…

    Running an internal DNS resolver is actually very cheap, almost every broadband CPE device runs or can run its own DNS proxy resolver. It's also a great source of information when …

    Circumventing your companies firewall is not a great idea in the first place. Additionally, if they have aggressive egress filtering, its likely that the only DNS communication wil…
