Vigil@nce - Qemu: buffer overflow of ne2000_receive
November 2015 by Vigil@nce
This bulletin was written by Vigil@nce : http://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
An attacker privileged in a guest system can generate a buffer
overflow in ne2000_receive of Qemu, in order to trigger a denial
of service, and possibly to run code on the host system.
Impacted products: Debian, Fedora, oVirt, QEMU, RHEL, SUSE Linux
Enterprise Desktop, SLES, Ubuntu.
Severity: 2/4.
Creation date: 15/09/2015.
DESCRIPTION OF THE VULNERABILITY
The Qemu product implements a NE2000 network device.
However, if the size of data is greater than
NE2000_MEM_SIZE(49152), an overflow occurs.
An attacker privileged in a guest system can therefore generate a
buffer overflow in ne2000_receive of Qemu, in order to trigger a
denial of service, and possibly to run code on the host system.
