[Libvirt-announce] Entering freeze for libvirt-1.2.14
by Daniel Veillard 30 Mar '15

30 Mar '15

I have tagged a release candidate 1 in git and generated signed tarballs and rpms at the usual place: ftp://libvirt.org/libvirt/ This seems to work normally in my limited testing but others need to give it a serious try ! I think I will do an RC2 on Monday, and if everything look file the final release will be on April 1st. Thanks in advance for reports about it !

[Libvirt-announce] LSN-2015-0002: small memory leak in ListAll APIs
by Eric Blake 17 Mar '15

17 Mar '15

Libvirt Security Notice: LSN-2015-0002 ====================================== Summary: small memory leak in ListAll APIs Reported on: 20150313 Published on: 20150316 Fixed on: 20150316 Reported by: Eric Blake <eblake(a)redhat.com> Patched by: Eric Blake <eblake(a)redhat.com> Description ----------- The interfaces remoteDispatchConnectListAllDomains, remoteDispatchDomainListAllSnapshots, remoteDispatchDomainSnapshotListAllChildren, remoteDispatchConnectListAllStoragePools, remoteDispatchStoragePoolListAllVolumes, remoteDispatchConnectListAllNetworks, remoteDispatchConnectListAllInterfaces, remoteDispatchConnectListAllNodeDevices, remoteDispatchConnectListAllNWFilters, remoteDispatchConnectListAllSecrets, and remoteDispatchNetworkGetDHCPLeases each have a guarantee that on a successful return, an array with a trailing NULL slot will be allocated, with the array size at least one larger than the return value. However, when using a remote connection where any of these calls returned a result of 0, the allocated array was leaked in the libvirtd server side of the API call. Impact ------ Since each ListAll API call is accessible to read-only clients, a client could repeatedly call the APIs to leak memory and attempt turning it into an out-of-memory denial of service against more privileged clients. In practice, though, since the leak is typically only 8 bytes per API call, an out-of-memory condition is unlikely to occur unless the client is calling the API so frequently as to be obvious that the client is attempting a denial of service long before memory is exhausted, so this vulnerability was not assigned a CVE. Workaround ---------- It is possible to guarantee that a memory leak cannot be escalated into a denial of service attack by preventing read-only connections and avoiding the use of fine-grained Access Control Lists (although this does not prevent the leaks, such a problem is no longer a security attack). Meanwhile, monitoring the libvirtd process for unexpected memory usage can be used to detect if any client is intentionally trying to exploit a memory leak, where restarting libvirtd is effective at avoiding issues where an eventual out-of-memory condition would cause adverse behavior.

[Libvirt-announce] ANNOUNCE: Libvirt Designer version 0.0.2 released
by Daniel P. Berrange 06 Mar '15

06 Mar '15

I'm pleased to announce the second release of the libvirt designer library, version 0.0.2 ftp://ftp.libvirt.org/libvirt/designer/libvirt-designer-0.0.2.tar.gz The release is signed ftp://ftp.libvirt.org/libvirt/designer/libvirt-designer-0.0.2.tar.gz.asc with the GPG key having the fingerprint DAF3 A6FD B26B 6291 2D0E 8E3F BE86 EBB4 1510 4FDF (4096R) In this release: - Bumped soname & version for ABI change - Remove use of deprecated libosinfo calls - Fix various memory leaks - Treat errors loading the libosinfo DB as non-fatal as some data may be successfully loaded - Improve building of libosinfo short-id from libvirt capabilities information - Expose the libosinfo DB object via a property on the domain object - Don't set PKG_CONFIG_PATH for g-ir-scanner - Auto-generate list of AUTHORS - Avoid redefining _FORTIFY_SOURCE macro - Fix & add gtk-doc introspection annotation - Add Vala APi binding - Add support for floppy & CDROM devices - Use libvirt style libtool versioning csheme - Add API to set list of installed drivers - Add API for querying supported devices - Remove many bogus assumptions in disk bus handling - Populate clock settings, input devices & console - Add API for enabling sound devices - Add AP ifor enabling choice of graphics backends - Add SPICE agent if using SPICE - Add API for enabling USB redirection - Add API for enabling smartcard devices - Add API for enabling video devices - Import latest compiler warnings from gnulib - Avoid using deprecated libvirt-gconfig APIs - Rename virtxml binary to virt-designer - Add API for choosing network backend type - Add further test cases for validing domain builder - Always build test programs The libvirt-designer library builds on top of the libvirt-gconfig and libosinfo libraries, to provide an API that assists applications in building guest domain configurations based on libosinfo policy. The intention is that it be usable from applications such as virt-manager and GNOME boxes which currently duplicate this kind of policy based configuration logic between them. It is still at an early experimental stage of development so it is liable to have further ABI incompatible changes in future releases, which will require recompiling applications and possibly source level changes too. Thanks to all the people who contributed towards this new release.
