Qemu · Qemu · CVE-2016-1714
**Name of the Vulnerable Software and Affected Versions**
QEMU versions prior to 2.4
**Description**
The issue concerns the `fw cfg write` and `fw cfg read` functions in QEMU, which can be exploited by guest OS users with the `CAP SYS RAWIO` privilege to cause a denial of service, including out-of-bounds read or write access and process crash, or possibly execute arbitrary code. This is achieved by providing an invalid current entry value in a firmware configuration.
**Recommendations**
For QEMU versions prior to 2.4, update to version 2.4 or later to resolve the issue. As a temporary workaround, consider restricting the use of the Firmware Configuration device emulation support to minimize the risk of exploitation.
