CVE-2017-15119
CVSS v3.1
8.6
High
| Vector | AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
QEMU versions prior to 2.11
Description
The issue is related to a denial of service problem in the Network Block Device (NBD) server. It can be triggered by a client sending large option requests, causing the server to waste CPU time. This could allow a remote attacker to keep the NBD server from serving other requests, resulting in a denial of service.
Recommendations
For versions prior to 2.11, update to version 2.11 or later to resolve the issue. As a temporary workaround, consider restricting access to the NBD server to minimize the risk of exploitation.
