Memory leak in hw/9pfs/9p-proxy.c in QEMU (aka Quick Emulator) allows local privileged guest OS users to cause a denial of service (host memory consumption and possibly QEMU process crash) by leveraging a missing cleanup operation in the proxy backend.
CVE-2016-9921 3 Debian, Qemu, Redhat 5 Debian Linux, Qemu, Enterprise Linux and 2 more 2025-04-12 6.5 Medium
Quick emulator (Qemu) built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to a divide by zero issue. It could occur while copying VGA data when cirrus graphics mode was set to be VGA. A privileged user inside guest could use this flaw to crash the Qemu process instance on the host, resulting in DoS.
CVE-2016-6888 3 Debian, Qemu, Redhat 5 Debian Linux, Qemu, Enterprise Linux and 2 more 2025-04-12 4.4 Medium
Integer overflow in the net_tx_pkt_init function in hw/net/net_tx_pkt.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (QEMU process crash) via the maximum fragmentation count, which triggers an unchecked multiplication and NULL pointer dereference.
CVE-2013-4151 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack 2025-04-12 N/A
The virtio_load function in virtio/virtio.c in QEMU 1.x before 1.7.2 allows remote attackers to execute arbitrary code via a crafted savevm image, which triggers an out-of-bounds write.
CVE-2015-8818 2 Qemu, Redhat 2 Qemu, Openstack 2025-04-12 5.5 Medium
The cpu_physical_memory_write_rom_internal function in exec.c in QEMU (aka Quick Emulator) does not properly skip MMIO regions, which allows local privileged guest users to cause a denial of service (guest crash) via unspecified vectors.
CVE-2013-4150 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack 2025-04-12 N/A
The virtio_net_load function in hw/net/virtio-net.c in QEMU 1.5.0 through 1.7.x before 1.7.2 allows remote attackers to cause a denial of service or possibly execute arbitrary code via vectors in which the value of curr_queues is greater than max_queues, which triggers an out-of-bounds write.
CVE-2016-4439 3 Canonical, Debian, Qemu 3 Ubuntu Linux, Debian Linux, Qemu 2025-04-12 6.7 Medium
The esp_reg_write function in hw/scsi/esp.c in the 53C9X Fast SCSI Controller (FSC) support in QEMU does not properly check command buffer length, which allows local guest OS administrators to cause a denial of service (out-of-bounds write and QEMU process crash) or potentially execute arbitrary code on the QEMU host via unspecified vectors.
CVE-2015-8817 2 Qemu, Redhat 2 Qemu, Openstack 2025-04-12 N/A
QEMU (aka Quick Emulator) built to use 'address_space_translate' to map an address to a MemoryRegionSection is vulnerable to an OOB r/w access issue.
