Vigil@nce - Xen: information disclosure via Heap Memory
June 2014 by Vigil@nce
This bulletin was written by Vigil@nce : http://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
An attacker located in a guest system can read a memory fragment
of Xen, in order to obtain sensitive information.
– Impacted products: Unix (platform)
– Severity: 1/4
– Creation date: 17/06/2014
DESCRIPTION OF THE VULNERABILITY
The Xen product uses memory pages, for the hypervisor and guest
systems.
However, pages which are not longer used by the hypervisor are not
reset, before being reused by guest systems.
An attacker located in a guest system can therefore read a memory
fragment of Xen, in order to obtain sensitive information.
