Vigil@nce - libvirt: NULL pointer dereference via lxcDomainGetMemoryParameters
January 2014 by Vigil@nce
This bulletin was written by Vigil@nce : http://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
An attacker can dereference a NULL pointer in
lxcDomainGetMemoryParameters of libvirt, in order to trigger a
denial of service.
Impacted products: openSUSE, Unix (platform)
Severity: 2/4
Creation date: 31/12/2013
DESCRIPTION OF THE VULNERABILITY
The libvirt library provides a standard interface on several
virtualization products (Xen, QEMU, KVM, etc.).
The lxcDomainGetMemoryParameters function is used to obtain
information about the memory. However, it does not check if a
pointer is NULL, before using it.
An attacker can therefore dereference a NULL pointer in
lxcDomainGetMemoryParameters of libvirt, in order to trigger a
denial of service.
