K75248350 : QEMU vulnerability CVE-2016-1714

Security Advisory Description

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. (CVE-2016-1714)
Impact
When exploited, an attacker with the appropriate privilege on the vCMP guest may cause the vCMP guest to crash, resulting in a denial of service (DoS). Additionally, an attacker with the appropriate privileges on the vCMP guest may potentially run arbitrary code with root privileges on the vCMP host.
