DEBIAN-CVE-2017-2620
Quick emulator QEMU before 2.8 built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to an out-of-bounds access issue. The issue could occur while copying VGA data in cirrusbitbltcputovideo. A privileged user inside guest could use this flaw to crash the QEMU process OR potentially...
Qemu: memory exhaustion through framebuffer update request message in VNC server
VNC server implementation in Quick Emulator QEMU was found to be vulnerable to an unbounded memory allocation issue, as it did not throttle the framebuffer updates sent to its client. If the client did not consume these updates, VNC server allocates growing memory to hold onto this data. A...
The vulnerability of the load_multiboot function (hw/i386/multiboot.c) in the QEMU hardware emulation driver allows a hacker to execute arbitrary code.
The vulnerability of the loadmultiboot function hw/i386/multiboot.c in the QEMU hardware emulation driver is caused by a numerical overflow. Exploiting this vulnerability allows a attacker operating on the local guest operating system to execute arbitrary code on the host operating system using a...
The vulnerability of the `megasas_mmio_write` function in the QEMU hardware emulation software allows a hacker to exert unpredictable effects.
The vulnerability of the megasasmmiowrite function in the QEMU hardware emulation software is caused by buffer overflow. Exploiting this vulnerability allows a remote attacker to exert unpredictable effects using unknown vectors...
QEMU Denial of Service Vulnerability (CNVD-2017-24371)
QEMU aka Quick Emulator is a set of simulation processor software developed by French programmer Fabrice Bellard. The software is fast and cross-platform. QEMU suffers from a denial of service vulnerability due to the program failing to properly clear pending packets. An attacker exploits the...
Qemu Denial of Service Vulnerability (CNVD-2017-30585)
QEMU aka Quick Emulator is a set of simulation processor software developed by French programmer Fabrice Bellard. The software is fast and cross-platform. A security vulnerability exists in the vga display update in QEMU versions 2.8.0 through 2.9.0. An attacker can exploit this vulnerability to...
UBUNTU-CVE-2017-9330
QEMU aka Quick Emulator before 2.9.0, when built with the USB OHCI Emulation support, allows local guest OS users to cause a denial of service infinite loop by leveraging an incorrect return value, a different vulnerability than CVE-2017-6505...
QEMU Denial of Service Vulnerability (CNVD-2017-08696 )
QEMU aka Quick Emulator is a suite of analog processor software developed by French programmer Fabrice Bellard. QEMU suffers from a denial of service vulnerability, which can be exploited by attackers to crash a QEMU instance, resulting in a denial of service...
QEMU Code Injection Vulnerability
QEMU aka Quick Emulator is a suite of analog processor software developed by French programmer Fabrice Bellard. A code injection vulnerability exists in QEMU versions prior to 2.9.0. Since the disasinsn function in target/i386/translate.c does not limit the size of instructions, an attacker could...
The vulnerability of the QEMU hardware emulation software, which allows a hacker to trigger a service failure
The vulnerability of the built-in virtual machine emulator for NIC, along with the QEMU hardware emulation driver VMWARE VMXNET3, is related to a memory leak. Exploiting this vulnerability allows an attacker to trigger a service failure memory consumption by disabling the vmxnet3 device...
QEMU 'hw/display/cirrus_vga_rop.h' has multiple memory corruption vulnerabilities
QEMU is an open source emulator software. Multiple memory corruption vulnerabilities exist in QEMU 'hw/display/cirrusvgarop.h', which allows local privileged users to submit a special request to crash the system...
UBUNTU-CVE-2017-5973
The xhcikickepctx function in hw/usb/hcd-xhci.c in QEMU aka Quick Emulator allows local guest OS privileged users to cause a denial of service infinite loop and QEMU process crash via vectors related to control transfer descriptor sequence...
The vulnerability of the QEMU hardware emulation software, which allows a hacker to trigger a service failure
The vulnerability of the virglresourceattachbacking function in the QEMU hardware/display/virtio-gpu-3d.c emulator is related to a memory leak. Exploiting this vulnerability can allow an attacker, operating locally, to cause a service failure memory consumption by using a large number of speciall...
DEBIAN-CVE-2017-5579
Memory leak in the serialexitcore 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...
Qemu: net: out of bounds read in net_checksum_calculate()
An out-of-bounds read-access flaw was found in the QEMU emulator built with IP checksum routines. The flaw could occur when computing a TCP/UDP packet's checksum, because a QEMU function used the packet's payload length without checking against the data buffer's size. A user inside a guest could...
