Final - K75248350: QEMU vulnerability CVE-2016-1714

Security Advisory

Original Publication Date: May 11, 2016
Updated Date: Oct 21, 2017

The security issue described in this article has been resolved or does not
affect any F5 products. There will be no further updates, unless new
information is discovered.

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.

Security Advisory Status

F5 Product Development has assigned ID 573778 (BIG-IP) to this vulnerability
and has evaluated the currently supported releases for potential vulnerability.
Additionally, BIG-IP iHealth may list Heuristic H75248350 on the Diagnostics >
Identified > High screen.

column, you can eliminate this vulnerability by upgrading to a version listed
in the Versions known to be not vulnerable column. If the table lists only an
older version than what you are currently running, or does not list a
non-vulnerable version, then no upgrade candidate currently exists.
