Description

An out-of-bounds heap buffer access flaw was found in the way the iSCSI Block driver in QEMU versions 2.12.0 before 4.2.1 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.

Affected configurations

• qemu qemu (>= 2.12.0 < 4.2.1) • redhat openstack 10 • redhat openstack 13 • redhat enterprise linux 7.0 • redhat enterprise linux 8.0 • debian debian linux 8.0 • debian debian linux 9.0 • opensuse leap 15.1
