CVE-2012-6075: qemu: e1000 driver buffer overflow when processing large packets when SBP and LPE flags are disabled

Severity: Critical

CVSS Score: 9.3

Buffer overflow in the e1000_receive function in the e1000 device driver (hw/e1000.c) in QEMU 1.3.0-rc2 and other versions, when the SBP and LPE flags are disabled, allows remote attackers to cause a denial of service (guest OS crash) and possibly execute arbitrary guest code via a large packet.
