CVSS v3.1 |
| Use-after-free vulnerability in hw/ide/ahci.c in QEMU, when built with IDE AHCI Emulation support, allows guest OS users to cause a denial of service (instance crash) or possibly execute arbitrary code via an invalid AHCI Native Command Queuing (NCQ) AIO command. |
| 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. |
| The (1) asn1_read_value_type and (2) asn1_read_value functions in GNU Libtasn1 before 3.6 allows context-dependent attackers to cause a denial of service (NULL pointer dereference and crash) via a NULL value in an ivalue argument. |
| 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. |
| Multiple unspecified vulnerabilities in the DER decoder in GNU Libtasn1 before 3.6, as used in GnuTLS, allow remote attackers to cause a denial of service (out-of-bounds read) via crafted ASN.1 data. |
| The patch_instruction function in hw/i386/kvmvapic.c in QEMU does not initialize the imm32 variable, which allows local guest OS administrators to obtain sensitive information from host stack memory by accessing the Task Priority Register (TPR). |
| The VGA module in QEMU improperly performs bounds checking on banked access to video memory, which allows local guest OS administrators to execute arbitrary code on the host by changing access modes after setting the bank register, aka the "Dark Portal" issue. |
| The asn1_get_bit_der function in GNU Libtasn1 before 3.6 does not properly report an error when a negative bit length is identified, which allows context-dependent attackers to cause out-of-bounds access via crafted ASN.1 data. |
| The vmxnet_tx_pkt_parse_headers function in hw/net/vmxnet_tx_pkt.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (buffer over-read) by leveraging failure to check IP header length. |
| Heap-based buffer overflow in the __nss_hostname_digits_dots function in glibc 2.2, and other 2.x versions before 2.18, allows context-dependent attackers to execute arbitrary code via vectors related to the (1) gethostbyname or (2) gethostbyname2 function, aka "GHOST." |
| The VGA emulator in QEMU allows local guest users to read host memory by setting the display to a high resolution. |
| The VNC websocket frame decoder in QEMU allows remote attackers to cause a denial of service (memory and CPU consumption) via a large (1) websocket payload or (2) HTTP headers section. |
| 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. |
| Apache Tomcat 6.x before 6.0.44, 7.x before 7.0.55, and 8.x before 8.0.9 does not properly handle cases where an HTTP response occurs before finishing the reading of an entire request body, which allows remote attackers to cause a denial of service (thread consumption) via a series of aborted upload attempts. |
| The pit_ioport_read in i8254.c in the Linux kernel before 2.6.33 and QEMU before 2.3.1 does not distinguish between read lengths and write lengths, which might allow guest OS users to execute arbitrary code on the host OS by triggering use of an invalid index. |
| Buffer overflow in the pcnet_receive function in hw/net/pcnet.c in QEMU, when a guest NIC has a larger MTU, allows remote attackers to cause a denial of service (guest OS crash) or execute arbitrary code via a large packet. |
| 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. |
| The C+ mode offload emulation in the RTL8139 network card device model in QEMU, as used in Xen 4.5.x and earlier, allows remote attackers to read process heap memory via unspecified vectors. |
| The set_pixel_format function in ui/vnc.c in QEMU allows remote attackers to cause a denial of service (crash) via a small bytes_per_pixel value. |
| The net_checksum_calculate function in net/checksum.c in QEMU allows local guest OS users to cause a denial of service (out-of-bounds heap read and crash) via the payload length in a crafted packet. |
