Bug Description

Nova is vulnerable to storage resource exhaustion via the Nova API log file. Invalid requests can be made, using extremely long server names, which result in the log file growing considerably large.

I've addressed this issue in Oneiric and Natty, but need a sponsor for Precise. Debdiff to soon follow.

---------------
nova (2012.1~rc2-0ubuntu1) precise; urgency=low

  [ Adam Gandelman ]
  * debian/control: Remove unncessary nova-cert dependency from nova-api.
    (LP: #965356)
  * debian/nova-common.postinst: Clean up spacing, remove redundant chown,
    set blanket 0700 nova.nova permissions on /etc/nova/
  * debian/nova-compute-{kvm, lxc, uml, xen}.postinst: Set proper permissions
    on /etc/nova/nova-compute.conf (LP: #861459)
  * debian/nova-common.postinst: Ensure default nova.sqlite database is not
    world-readable.
  * debian/{rules, nova-common.{install, postinst}}: Install api-paste.ini 0600
    with nova-common (in prepartion for proper nova-api-* package separation)
  * debian/{nova-common.nova-manage.logrotate,
    nova-network.nova-dhcpbridge.logrotate, rules}: Add lograte files,
    override_dh_installlogrotate. (LP: #942646)
  * Add manpage stubs for nova-api-ec2, nova-api-metadata,
    nova-api-os-{volume, compute}, nova-rootwrap. Use sphinx built manpage
    for nova-manage (nova-common.manpages)
  * debian/nova-compute-{kvm, xen, uml, qemu}.postinst: Remove calls to
    adduser since this is already handled from nova-compute.postsinst in a
    vendor neutral way. Silences lintian errors regarding adduser dependency

  [ Chuck Short ]
  * New upstream version.
  * debian/patches/libvirt-use-console-pipe.patch: Dropped.
  * debian/patches/nova-console-monitor.patch: Add console-monitor
    option.
  * debian/nova.conf: Enable use_console_monitor
  * debian/patches/fix-ubuntu-tests.patch: Fix nova testsuite.
  * debian/rules: fail package build if testsuite fails.
  * debian/patches/validate_server_name_length.patch: Dropped no longer
    needed.
  * debian/patches/fix-docs-build-without-network.patch: Some docs need
    a network connection in order to build. Disable fetching docs from
    the internet.
  * debian/patches/0001-fix-useexisting-deprecation-warnings.patch:
    Remove deprecated warnings with sqlalchemy.

  [ Tyler Hicks ]
  * SECURITY UPDATE: Denial of service via resource exhaustion in nova-api
    (LP: #968411)
    - debian/patches/validate_server_name_length.patch: Limit server names
      to a maximum of 255 characters to prevent nova-api log files from
      exhausting storage space. Based on upstream patch.
