This bug is actually security-critical. I'm copying the Ubuntu-Security team, and updating the changelog for security update publication.
Basically, a guest running virtio networking and a linux kernel <= 2.6.25 (eg hardy) can be remotely DoS'd by any other user on the network flooding an open network port (eg 22) with traffic. The DoS causes crash in the kvm process. Because the guest's operating system was not shut down cleanly, unwritten buffers or dirty filesystem operations could yield data loss in the guest. Attaching a debdiff for the security team to upload to the security- prosed pocket. :-Dustin ** Attachment added: "out" http://launchpadlibrarian.net/34719238/out -- kvm crash when using virtio for network, hardy guest https://bugs.launchpad.net/bugs/458521 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
