CVE-2020-1711
First published: Thu Jan 23 2020(Updated: )
An out-of-bounds heap buffer access flaw was found in the way the iSCSI Block driver in QEMU handled a response coming from an iSCSI server while checking the status of a Logical Address Block (LBA) in an iscsi_co_block_status() routine. A remote user could use this flaw to crash the QEMU process, resulting in a denial of service or potential execution of arbitrary code with privileges of the QEMU process on the host.
