CVE-2018-19364 |
hw/9pfs/cofile.c and hw/9pfs/9p.c in QEMU can modify an fid path while it is being accessed by a second thread, leading to (for example) a use-after-free outcome. Published: December 13, 2018; 2:29:00 PM -0500 |

CVE-2018-16867 |
A flaw was found in qemu Media Transfer Protocol (MTP) before version 3.1.0. A path traversal in the in usb_mtp_write_data function in hw/usb/dev-mtp.c due to an improper filename sanitization. When the guest device is mounted in read-write mode, this allows to read/write arbitrary files which may lead do DoS scenario OR possibly lead to code execution on the host.

CVE-2018-12617 |
qmp_guest_file_read in qga/commands-posix.c and qga/commands-win32.c in qemu-ga (aka QEMU Guest Agent) in QEMU 2.12.50 has an integer overflow causing a g_malloc0() call to trigger a segmentation fault when trying to allocate a large memory chunk. The vulnerability can be exploited by sending a crafted QMP command (including guest-file-read with a large count value) to the agent via the listening socket. Published: June 21, 2018; 2:29:00 PM -0400 |
V3.1: 7.5 HIGH V2.0: 5.0 MEDIUM |
CVE-2018-11806 |

V3.1: 8.2 HIGH V2.0: 7.2 HIGH |
CVE-2018-7858 |
Quick Emulator (aka QEMU), when built with the Cirrus CLGD 54xx VGA Emulator support, allows local guest OS privileged users to cause a denial of service (out-of-bounds access and QEMU process crash) by leveraging incorrect region calculation when updating VGA display. Published: March 12, 2018; 5:29:01 PM -0400 |
V3.1: 5.5 MEDIUM V2.0: 2.1 LOW |
CVE-2018-7550 |
The load_multiboot function in hw/i386/multiboot.c in Quick Emulator (aka QEMU) allows local guest OS users to execute arbitrary code on the QEMU host via a mh_load_end_addr value greater than mh_bss_end_addr, which triggers an out-of-bounds read or write memory access. Published: March 01, 2018; 12:29:00 PM -0500 |

CVE-2017-15124 |
VNC server implementation in Quick Emulator (QEMU) 2.11.0 and older 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 malicious remote VNC client could use this flaw to cause DoS to the server host. Published: January 09, 2018; 4:29:00 PM -0500 |
