CVE-2016-2140 Detail

Modified

This vulnerability has been modified since it was last analyzed by the NVD. It is awaiting reanalysis which may result in further changes to the information provided.

Description

The libvirt driver in OpenStack Compute (Nova) before 2015.1.4 (kilo) and 12.0.x before 12.0.3 (liberty), when using raw storage and use_cow_images is set to false, allows remote authenticated users to read arbitrary files via a crafted qcow2 header in an ephemeral or root disk.

Action	Type	Old Value	New Value
Changed	Description	An information-exposure flaw was found in the OpenStack Compute (nova) resize and migrate functionality. An authenticated user could write a malicious qcow header to an ephemeral or root disk, referencing a block device as a backing file. With a subsequent resize or migration, file system content on the specified device would be leaked to the user. Only setups using libvirt with raw storage and "use_cow_images = False" were affected.
