CVE-2016-5126

Heap-based buffer overflow in the iscsi_aio_ioctl function in block/iscsi.c in QEMU allows local guest OS users to cause a denial of service (QEMU process crash) or possibly execute arbitrary code via a crafted iSCSI asynchronous I/O ioctl call.

CVE-2016-5403

The virtqueue_pop function in hw/virtio/virtio.c in QEMU allows local guest OS administrators to cause a denial of service (memory consumption and QEMU process crash) by submitting requests without waiting for completion.

CVE-2017-9375

QEMU, when built with USB xHCI controller emulator support, allows local guest OS privileged users to cause a denial of service (infinite recursive call) via vectors involving control transfer descriptors sequencing.

CVE-2019-12068

QEMU scsi disk backend: lsi: exit infinite loop while executing script

CVE-2019-12155

interface_release_resource in hw/display/qxl.c in QEMU has a NULL pointer dereference.

CVE-2019-13164

qemu-bridge-helper.c in QEMU does not ensure that a network interface name (obtained from bridge.conf or a --br=bridge option) is limited to the IFNAMSIZ size, which can lead to an ACL bypass.

CVE-2019-14378

ip_reass in ip_input.c in libslirp 4.0.0 has a heap-based buffer overflow via a large packet because it mishandles a case involving the first fragment.

CVE-2019-15890

libslirp 4.0.0, as used in QEMU, has a use-after-free in ip_reass in ip_input.c.

For Debian 8 Jessie, these problems have been fixed in version 1:2.1+dfsg-12+deb8u12.

We recommend that you upgrade your qemu packages.
