Mandriva Linux Security Advisory 2015-115 - The LXC driver in libvirt 1.0.1 through 1.2.1 allows local users to delete arbitrary host devices via the virDomainDeviceDettach API and a symlink attack on /dev in the container; via the virDomainDeviceAttach API and a symlink attack on /dev in the container; and cause a denial of service (shutdown or reboot host OS) via the virDomainReboot API and a symlink attack on /dev/initctl in the container, related to paths under /proc//root and the virInitctlSetRunLevel function. Various other issues have also been addressed.

Mandriva Linux Security Advisory 2014-097 - The LXC driver in libvirt 1.0.1 through 1.2.1 allows local users to delete arbitrary host devices via the virDomainDeviceDettach API and a symlink attack on /dev in the container; via the virDomainDeviceAttach API and a symlink attack on /dev in the container; and cause a denial of service (shutdown or reboot host OS) via the virDomainReboot API and a symlink attack on /dev/initctl in the container, related to paths under /proc//root and the virInitctlSetRunLevel function. libvirt was patched to prevent expansion of entities when parsing XML files. This vulnerability allowed malicious users to read arbitrary files or cause a denial of service. The updated packages have been upgraded to the 1.1.3.5 version and patched to correct these issues.

Ubuntu Security Notice 2209-1 - It was discovered that libvirt incorrectly handled symlinks when using the LXC driver. An attacker could possibly use this issue to delete host devices, create arbitrary nodes, and shutdown or power off the host. Marian Krcmarik discovered that libvirt incorrectly handled seamless SPICE migrations. An attacker could possibly use this issue to cause a denial of service. Various other issues were also addressed.
