Debian Security Advisory DSA-2650-1 security@debian.org http://www.debian.org/security/ Yves-Alexis Perez March 15, 2013 http://www.debian.org/security/faq


Package : libvirt-bin Vulnerability : files and device nodes ownership change to kvm group Problem type : local Debian-specific: yes CVE ID : CVE-2013-1766 Debian Bug : 701649

Bastian Blank discovered that libvirtd, a daemon for management of virtual machines, network and storage, would change ownership of devices files so they would be owned by user libvirt-qemu and group kvm, which is a general purpose group not specific to libvirt, allowing unintended write access to those devices and files for the kvm group members.

For the stable distribution (squeeze), this problem has been fixed in version 0.8.3-5+squeeze4.

For the testing distribution (wheezy), this problem has been fixed in version 0.9.12-11.

For the unstable distribution (sid), this problem has been fixed in version 0.9.12-11.

We recommend that you upgrade your libvirt-bin packages.
