CVE-2011-4111

Estado: ModificadaMedia (6.8)—

Buffer overflow in the ccid_card_vscard_handle_message function in hw/ccid-card-passthru.c in QEMU before 0.15.2 and 1.x before 1.0-rc4 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted VSC_ATR message.
