   SUSE Security Update: Security update for Openstack Nova

Announcement ID:    SUSE-SU-2013:0718-1
Rating:             moderate
References:         #803351 #806240 #808622 
Affected Products:
                    SUSE Cloud 1.0

   An update that contains security fixes can now be installed.


   Openstack Nova has been updated to fix the following
   security issues:

   * CVE-2013-0280: Jonathan Murray from NCC Group, Joshua
   Harlow from Yahoo! and Stuart Stent independently reported
   a vulnerability in the parsing of XML requests in Keystone,
   Nova and Cinder. By using entities in XML requests, an
   unauthenticated attacker may consume excessive resources on
   the Keystone, Nova or Cinder API servers, resulting in a
   denial of service and potentially a crash. Authenticated
   attackers may also leverage XML entities to read the
   content of a local file on the Keystone API server. This
   only affects servers with XML support enabled.
   * CVE-2013-0335: Loganathan Parthipan (HP) and Rohit
   Karajgi (NTT Data) independently reported a vulnerability
   in Nova. If a user requests a console and then deletes the
   VM, it is possible that the console token could allow
   connectivity to a different VM before the console token
   expires if the VNC port gets reused in that time period.
   This issue can be worked around by disabling VNC support.
   * CVE-2013-1838: Vish Ishaya reported a vulnerability
   in Nova where there is no quota for Fixed IPs. Previously
   the instance quota acted as a proxy for a Fixed IP quota,
   but if your configuration allows an instance to consume
   more than one Fixed IP via an extension such as multinic
   then this is no longer true. Running out of Fixed IPs would
   result in not being able to spawn new instances.
