Vigil@nce - QEMU: buffer overflow of stellaris_enet_receive
June 2016 by Vigil@nce
This bulletin was written by Vigil@nce : https://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
A remote attacker can send large packets to generate a buffer
overflow in the stellaris_enet driver of QEMU, in order to trigger
a denial of service, and possibly to run code.
– Impacted products: Fedora, QEMU, Ubuntu.
– Severity: 2/4.
– Creation date: 11/04/2016.
DESCRIPTION OF THE VULNERABILITY
The QEMU product offers a network device compatible with Stellaris.
However, if the size of received packets is superior to 2048 bytes
(with Large MTU), an overflow occurs in the
stellaris_enet_receive() function.
A remote attacker can therefore send large packets to generate a
buffer overflow in the stellaris_enet driver of QEMU, in order to
trigger a denial of service, and possibly to run code.
