Vigil@nce - libvirt: descriptor leak via PoolListAllVolumes

May 2013 by Vigil@nce

This bulletin was written by Vigil@nce : http://vigilance.fr/offer

SYNTHESIS OF THE VULNERABILITY

An attacker can create a file descriptor leak in the remoteDispatchStoragePoolListAllVolumes() function of libvirt, in order to trigger a denial of service.

- Impacted products: Fedora, RHEL, Unix (platform)
- Severity: 2/4
- Creation date: 16/05/2013

DESCRIPTION OF THE VULNERABILITY

The libvirt library provides a standard interface on several virtualization products (Xen, QEMU, KVM, etc.).

The remoteDispatchStoragePoolListAllVolumes() function of the daemon/remote.c file lists storage volumes. However, on each call, it does not free two file descriptors.

An attacker can therefore create a file descriptor leak in the remoteDispatchStoragePoolListAllVolumes() function of libvirt, in order to trigger a denial of service.
