17 Nov '14

libvirt 1.1.3.8 maintenance release is now available. This is libvirt 1.1.3 with additional bugfixes that have accumulated upstream since the initial release. This release can be downloaded at: http://libvirt.org/sources/stable_updates/libvirt-1.1.3.8.tar.gz I originally release 1.1.3.7, but then when I attempted to rebuild it I hit a compile error. Really not sure why it didn't hit me during before. So 1.1.3.8 is a brown paper bag release. Changes in version 1.1.3.7: * CVE-2014-7823: dumpxml: security hole with migratable flag * node_device_udev: Try harder to get human readable vendor:product * tests: don't fail with newer gnutls * Fix crash in virsystemdtest with dbus 1.7.6 * domain_conf: fix domain deadlock * CVE-2014-3633: qemu: blkiotune: Use correct definition when looking up disk Changes in version 1.1.3.8: * tests: Fix compilation For info about past maintenance releases, see: http://wiki.libvirt.org/page/Maintenance_Releases Thanks, Cole

[Libvirt-announce] LSN-2014-0007: CVE-2014-7823 virDomainGetXMLDesc leaks VNC passwords
by Eric Blake 11 Nov '14

11 Nov '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Libvirt Security Notice: LSN-2014-0007 ====================================== Summary: virDomainGetXMLDesc leaks VNC passwords Reported on: 20141031 Published on: 20141105 Fixed on: 20141106 Reported by: Eric Blake <eblake(a)redhat.com> Patched by: Eric Blake <eblake(a)redhat.com> See also: CVE-2014-7823 Description - ----------- At the time the VIR_DOMAIN_XML_MIGRATABLE flag was added to the virDomainGetXMLDesc API, the qemu implementation chose to make the flag always imply the VIR_DOMAIN_XML_SECURE flag. The secure flag had been previously deemed unsafe to use from a read-only connection; however, because the new migratable flag is not restricted against use by read-only clients, a client can use the new flag to bypass the restrictions placed on the use of the old flag. Impact - ------ A read-only client can trigger an information leak of data that should normally require the use of VIR_DOMAIN_XML_SECURE to access. Fortunately, the only data in this category is the value of an optional VNC password. Workaround - ---------- VNC passwords are notoriously weak (they are capped at an 8 byte maximum length; the VNC protocol sends them in plaintext over the network; and FIPS mode execution prohibits the use of a VNC password), so it is recommended that users not create domains with a VNC password in the first place. Domains that do not use VNC passwords do not suffer from information leaks; the use of SPICE connections is recommended not only because it avoids the leak, but also because SPICE provides better features than VNC for a guest graphics device. It is also possible to prevent the leak by denying access to read-only clients; for builds of libvirt that support fine-grained ACLs, this course of action requires ensuring that no user is granted the 'read' ACL privilege without also having the 'read_secure' privilege.
