CVE-2013-2016 (GCVE-0-2013-2016)
Vulnerability from cvelistv5 – Published: 2019-12-30 21:47 – Updated: 2024-08-06 15:20

Summary
A flaw was found in the way qemu v1.3.0 and later (virtio-rng) validates addresses when guest accesses the config space of a virtio device. If the virtio device has zero/small sized config space, such as virtio-rng, a privileged guest user could use this flaw to access the matching host's qemu address space and thus increase their privileges on the host.
Severity ?

Vulnerability from cvelistv5 – Published: 2018-07-27 21:00 – Updated: 2024-08-06 02:59
VLAI?
Summary
A heap buffer overflow flaw was found in QEMU's Cirrus CLGD 54xx VGA emulator's VNC display driver support before 2.9; the issue could occur when a VNC client attempted to update its display after a VGA operation is performed by a guest. A privileged user/process inside a guest could use this flaw to crash the QEMU process or, potentially, execute arbitrary code on the host with privileges of the QEMU process.

CVE-2017-15118 (GCVE-0-2017-15118)
Vulnerability from cvelistv5 – Published: 2018-07-27 21:00 – Updated: 2024-08-05 19:50
VLAI?
Summary
A stack-based buffer overflow vulnerability was found in NBD server implementation in qemu before 2.11 allowing a client to request an export name of size up to 4096 bytes, which in fact should be limited to 256 bytes, causing an out-of-bounds stack write in the qemu process. If NBD server requires TLS, the attacker cannot trigger the buffer overflow without first successfully negotiating TLS.
Severity ?

Summary
A stack buffer overflow flaw was found in the Quick Emulator (QEMU) before 2.9 built with the Network Block Device (NBD) client support. The flaw could occur while processing server's response to a 'NBD_OPT_LIST' request. A malicious NBD server could use this issue to crash a remote NBD client resulting in DoS or potentially execute arbitrary code on client host with privileges of the QEMU process.

CVE-2017-15119 (GCVE-0-2017-15119)
Vulnerability from cvelistv5 – Published: 2018-07-27 16:00 – Updated: 2024-08-05 19:50
VLAI?
Summary
The Network Block Device (NBD) server in Quick Emulator (QEMU) before 2.11 is vulnerable to a denial of service issue. It could occur if a client sent large option requests, making the server waste CPU time on reading up to 4GB per request. A client could use this flaw to keep the NBD server from serving other requests, resulting in DoS.

Summary
An assertion-failure flaw was found in Qemu before 2.10.1, in the Network Block Device (NBD) server's initial connection negotiation, where the I/O coroutine was undefined. This could crash the qemu-nbd server if a client sent unexpected data during connection negotiation. A remote user or process could use this flaw to crash the qemu-nbd server resulting in denial of service.

CVE-2017-15124 (GCVE-0-2017-15124)
Vulnerability from cvelistv5 – Published: 2018-01-09 21:00 – Updated: 2024-08-05 19:50
VLAI?
Summary
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.
Severity ?
No CVSS data available.
