CVE-2016-1714: Oracle Linux

High severity, CVSS 8.1. EPSS: 6.1% chance of exploitation in the next 30 days.

The (1) fw_cfg_write and (2) fw_cfg_read functions in hw/nvram/fw_cfg.c in QEMU before 2.4, when built with the Firmware Configuration device emulation support, allow guest OS users with the CAP_SYS_RAWIO privilege to cause a denial of service (out-of-bounds read or write access and process crash) or possibly execute arbitrary code via an invalid current entry value in a firmware configuration.

Affected products

• Oracle Linux: version 6 only; version 7 only
• Qemu Qemu: up to and including 2.3.0
• Red Hat Openstack: version 5.0 only
