Vigil@nce - QEMU: infinite loop of e1000
February 2016 by Vigil@nce
This bulletin was written by Vigil@nce : http://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
An attacker in a guest system can generate an infinite loop in the
e1000 implementation of QEMU, in order to trigger a denial of
service on the host system.
Impacted products: QEMU, Ubuntu.
Severity: 1/4.
Creation date: 20/01/2016.
DESCRIPTION OF THE VULNERABILITY
The QEMU product implements the support of e1000 network devices.
However, by using invalid TDH/RDH values, an infinite loop occurs
in the hw/net/e1000.c file.
An attacker in a guest system can therefore generate an infinite
loop in the e1000 implementation of QEMU, in order to trigger a
denial of service on the host system.
