Vigil@nce - QEMU: information disclosure via RTL8139
August 2015 by Vigil@nce
This bulletin was written by Vigil@nce : http://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
A local attacker can read a memory fragment of RTL8139 of QEMU, in
order to obtain sensitive information.
Impacted products: Fedora, QEMU, Xen.
Severity: 1/4.
Creation date: 03/08/2015.
DESCRIPTION OF THE VULNERABILITY
The QEMU product can emulate a RTL8139 network device.
However, several functions of the hw/rtl8139.c file do not
initialize a memory area before returning it to the user.
A local attacker can therefore read a memory fragment of RTL8139
of QEMU, in order to obtain sensitive information.
