CVE-2015-6855

HIGH

QEMU < 2.4.1 - Denial of Service via ATAPI IDE Command Handling

Title source: llm
STIX 2.1

Description

hw/ide/core.c in QEMU does not properly restrict the commands accepted by an ATAPI device, which allows guest users to cause a denial of service or possibly have unspecified other impact via certain IDE commands, as demonstrated by a WIN_READ_NATIVE_MAX command to an empty drive, which triggers a divide-by-zero error and instance crash.
