Severity Rating: CVSS v3Base Score: See below for individual scores

Affected products:
EMC ScaleIO versions before

EMC ScaleIO version contains fixes for multiple security
vulnerabilities that could potentially be exploited by malicious users to
compromise the affected system.

EMC ScaleIO versions before could be vulnerable to the following

Privilege escalation  vulnerability (CVE-2016-9867)

A low-privileged local attacker may be able to modify the kernel memory
in the SCINI driver and may achieve code execution to escalate privileges
to root on ScaleIO Data Client (SDC) servers.
CVSSv3: 7.8 (AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H)

Denial-of-service vulnerability via IOCTL calls (CVE-2016-9868)

A low-privileged local attacker may cause a denial-of-service by generating
a kernel panic in the SCINI driver using IOCTL calls which may render the
ScaleIO Data Client (SDC) server unavailable until the next reboot.
CVSSv3: 4.7 (AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H)

Denial-of-service through configuration API (CVE-2016-9869)

Incorrect permissions on the SCINI driver may allow a low-privileged local
attacker to modify the configuration and render the ScaleIO Data Client
(SDC) server unavailable.
CVSSv3: 4.7 (AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H)

The following EMC ScaleIO release contains resolutions to these
	EMC ScaleIO version

EMC recommends all customers upgrade at the earliest opportunity. For
those that are unable to upgrade we recommend customers to change the
access permission to 600 as follows:

	For each SDC, please execute the following SHELL command:
chmod 600 /dev/scini


1.	This should be executed "as-is" (do not add anything else to
the command).
2.	This command should be executed after every reload of the SDC or
after reboot
3.	Once upgraded to it is all set and no need to use this
