CVSS v3.1 |
| The disas_insn function in target/i386/translate.c in QEMU before 2.9.0, when TCG mode without hardware acceleration is used, does not limit the instruction size, which allows local users to gain privileges by creating a modified basic block that injects code into a setuid program, as demonstrated by procmail. NOTE: the vendor has stated "this bug does not violate any security guarantees QEMU makes. |
| QEMU (aka Quick Emulator), 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. |
| qemu-nbd in QEMU (aka Quick Emulator) does not ignore SIGPIPE, which allows remote attackers to cause a denial of service (daemon crash) by disconnecting during a server-to-client reply attempt. |
| The eepro100 emulator in QEMU qemu-kvm blank allows local guest users to cause a denial of service (application crash and infinite loop) via vectors involving the command block list. |
| Memory leak in the serial_exit_core function in hw/char/serial.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (host memory consumption and QEMU process crash) via a large number of device unplug operations. |
| Local privilege escalation vulnerability in the Gentoo QEMU package before 2.5.0-r1. |
| An integer overflow and buffer overflow issues were found in the ACPI Error Record Serialization Table (ERST) device of QEMU in the read_erst_record() and write_erst_record() functions. Both issues may allow the guest to overrun the host buffer allocated for the ERST memory device. A malicious guest could use these flaws to crash the QEMU process on the host. |
| An out-of-bounds read flaw was found in the QXL display device emulation in QEMU. The qxl_phys2virt() function does not check the size of the structure pointed to by the guest physical address, potentially reading past the end of the bar space into adjacent pages. A malicious guest user could use this flaw to crash the QEMU process on the host causing a denial of service condition. |
| The get_cmd function in hw/scsi/esp.c in the 53C9X Fast SCSI Controller (FSC) support in QEMU does not properly check DMA length, which allows local guest OS administrators to cause a denial of service (out-of-bounds write and QEMU process crash) via unspecified vectors, involving an SCSI command. |
| The (1) mptsas_config_manufacturing_1 and (2) mptsas_config_ioc_0 functions in hw/scsi/mptconfig.c in QEMU (aka Quick Emulator) allow local guest OS administrators to cause a denial of service (QEMU process crash) via vectors involving MPTSAS_CONFIG_PACK. |
| The mcf_fec_do_tx function in hw/net/mcf_fec.c in QEMU (aka Quick Emulator) does not properly limit the buffer descriptor count when transmitting packets, which allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) via vectors involving a buffer descriptor with a length of 0 and crafted values in bd.flags. |
| hw/scsi/vmw_pvscsi.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (out-of-bounds access or infinite loop, and QEMU process crash) via a crafted page count for descriptor rings. |
| Integer overflow in the qcow_open function in block/qcow.c in QEMU before 1.7.2 allows remote attackers to cause a denial of service (crash) via a large L2 table in a QCOW version 1 image. |
| Memory leak in the virtio_gpu_resource_create_2d function in hw/display/virtio-gpu.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (memory consumption) via a large number of VIRTIO_GPU_CMD_RESOURCE_CREATE_2D commands. |
| Integer overflow in the qcow_open function in block/qcow.c in QEMU before 1.7.2 allows local users to cause a denial of service (crash) and possibly execute arbitrary code via a large image size, which triggers a buffer overflow or out-of-bounds read. |
| Heap-based buffer overflow in the virtio_load function in hw/virtio/virtio.c in QEMU before 1.7.2 might allow remote attackers to execute arbitrary code via a crafted config length in a savevm image. |
| The rc4030_write function in hw/dma/rc4030.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (divide-by-zero error and QEMU process crash) via a large interval timer reload value. |
| Integer overflow in the virtio_net_handle_mac function in hw/net/virtio-net.c in QEMU 2.0 and earlier allows local guest users to execute arbitrary code via a MAC addresses table update request, which triggers a heap-based buffer overflow. |
| Buffer overflow in the ccid_card_vscard_handle_message function in hw/ccid-card-passthru.c in QEMU before 0.15.2 and 1.x before 1.0-rc4 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted VSC_ATR message. |
| Array index error in the virtio_load function in hw/virtio/virtio.c in QEMU before 1.7.2 allows remote attackers to execute arbitrary code via a crafted savevm image. |
