CVE-2010-2238 [MEDIUM] libvirt regression
Title: libvirt regression
Summary: This update restores 'host_device' support for domain XML on Ubuntu 10.04
LTS.
USN-1008-1 fixed vulnerabilities in libvirt. The upstream fixes for
CVE-2010-2238 changed the behavior of libvirt such that the domain
XML could not specify 'host_device' as the qemu sub-type. While libvirt
0.8.3 and later will longer support specifying this sub-type, this
update restores the old behavior on Ubuntu 10.04 LTS.
We apologize for the inconvenience.
Original advisory details:
It was discovered that libvirt would probe disk backing stores without
consulting the defined format for the disk. A privileged attacker in the
guest could exploit this to read arbitrary files on the host. This issue

[MEDIUM] Virtinst update
Title: Virtinst update
Summary: Updated virtinst for use with the new libvirt.
Libvirt in Ubuntu 10.04 LTS now no longer probes qemu disks for the image
format and defaults to 'raw' when the format is not specified in the XML.
This change in behavior breaks virt-install --import because virtinst in
Ubuntu 10.04 LTS did not allow for specifying a disk format and does not
specify a format in the XML. This update adds the 'format=' option when
specifying a disk. For example, to import an existing VM which uses a qcow2
disk format, use somthing like the following:
virt-install --connect=qemu:///session --name test-import --ram=256 \
--disk path=,format=qcow2 --import
For more information, see man 1 virt-install.

CVE-2010-2239 libvirt: not setting user defined backing store format when creating new image
It was found that libvirt did not explicitly set the user defined backing store
format when creating new image. This results in images being created with an
potentialy insecure configuration, preventing applications from opening backing
stores without resorting to probing. A priviledged guest user could use this flaw
to access arbitrary files on the host.
Discussion:
This issue affects libvirt >= 0.6.0.
