Libvirt Security Notice: LSN-2014-0009 ====================================== Summary: crash when using virStorageVolUpload Reported on: 20141202 Published on: 20141203 Fixed on: 20141203 Reported by: Pei Zhang <pzhang(a)redhat.com> Patched by: Luyao Huang <lhuang(a)redhat.com> See also: CVE-2014-8135 Description ----------- Incorrect parameter validation of the virStorageVolUpload command could cause libvirtd to attempt to dereference NULL. Impact ------ When using fine-grained ACLs, a user that is permitted to modify storage volumes but not create arbitrary domains can use bogus parameters to cause a denial of service attack against more privileged users. Workaround ---------- Passing valid parameters to virStorageVolUpload will not trigger a problem. It is also possible to prevent the denial of service by stopping the use of the fine grained access control mechanism, or by not granting users the storage_vol:data_write permission if they do not also have the domain:write permission; doing this will not prevent the crash for invalid parameters, but such a crash is no longer a security attack.

[Libvirt-announce] LSN-2014-0008: CVE-2014-8131 deadlock or segfault in virConnectGetAllDomainStats

Libvirt Security Notice: LSN-2014-0008 ====================================== Summary: deadlock or segfault in virConnectGetAllDomainStats Reported on: 20141127 Published on: 20141205 Fixed on: 20141211 Reported by: Martin Kletzander <mkletzan(a)redhat.com> Patched by: Martin Kletzander <mkletzan(a)redhat.com>, Francesco Romani <fromani(a)redhat.com> See also: CVE-2014-8131 Description ----------- When using fine-grained ACLs to restrict users from accessing all domains, a logic bug in the qemu implementation of virConnectGetAllDomainStats could result in incorrect lock management of the next domain inspected after a domain that was skipped due to ACL restrictions. Impact ------ A restricted client can trigger a denial of service against a more privileged user when libvirtd goes into deadlock when trying to lock an incorrectly locked domain, or crashes when trying to unlock a domain that was not locked. Workaround ---------- Stop use of the fine grained access control mechanism, or stop trying to use access control to restrict the set of domains that an authorized client can see.

[Libvirt-announce] ANNOUNCE: libvirt-glib release 0.2.0
by Daniel P. Berrange 15 Dec '14

15 Dec '14

I am pleased to announce that a new release of the libvirt-glib package, version 0.2.0, is now available from ftp://libvirt.org/libvirt/glib/ The packages are GPG signed with Key fingerprint: DAF3 A6FD B26B 6291 2D0E 8E3F BE86 EBB4 1510 4FDF (4096R) Changes in this release: - Support keyboard input device config - Annotate some unused parameters - Add support for new graphics attach API libvirt-glib comprises three distinct libraries: - libvirt-glib - Integrate with the GLib event loop and error handling - libvirt-gconfig - Representation of libvirt XML documents as GObjects - libvirt-gobject - Mapping of libvirt APIs into the GObject type system NB: While libvirt aims to be API/ABI stable forever, with libvirt-glib we are not currently guaranteeing that libvirt-glib libraries are permanently API/ABI stable. That said we do not expect to break the API/ABI for the forseeable future and will always strive avoid it. Follow up comments about libvirt-glib should be directed to the regular libvir-list(a)redhat.com development list. Thanks to all the people involved in contributing to this release.

[Libvirt-announce] Entering freeze for 1.2.11, rc1 available
by Daniel Veillard 11 Dec '14

11 Dec '14

As planned, I tagged 1.2.11-rc1 in git and made signed tarballs and rpms available at the usual place: ftp://libvirt.org/libvirt/ This seems to work fine in my limited testing, but please give it a serious try ! I understand Peter concerns w.r.t. the parallels patches, IMHO if this doesn't touch common code and is fine by the maintainers, then pushing in time for rc2 is reasonable even if we are past freeze. The plan is to put out an rc2 in a couple of days and get the final release this w.e. unless there is a serious issue blocking it. thanks in advance for testing and reports !

by Cole Robinson 16 Nov '14

16 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 10 Nov '14

10 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.

[Libvirt-announce] Entering freeze and release of cadidate release 1 of 1.2.10
by Daniel Veillard 31 Oct '14

31 Oct '14

As planned beginning of this week, I just tagged 1.2.10-rc1 in git and pushed signed tarballs and rpms to the usual place: ftp://libvirt.org/libvirt/ The plan would be to get the rc2 out this friday, and push the release on monday if everything looks okay. In my own tests, my guest lost network connectivity, I'm not sure if it is a temporary problem on my side or something more serious in the current code, so please give it a try and report, thanks, Daniel -- Daniel Veillard | Open Source and Standards, Red Hat veillard(a)redhat.com | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | virtualization library http://libvirt.org/
