Synopsis

The GIGABYTE OC GURU II software installed on the remote host is affected by multiple vulnerabilities.

Description

The version of GIGABYTE OC GURU II installed on the remote host is 2.08. It is, therefore, affected by multiple vulnerabilities as referenced in GIGABYTE security advisory 1801:

 - The GDrv low-level driver in GIGABYTE APP Center v1.05.21 and earlier, AORUS GRAPHICS ENGINE before 1.57, XTREME GAMING ENGINE before 1.26, and OC GURU II v2.08 exposes ring0 memcpy-like functionality that could allow a local attacker to take complete control of the affected system. (CVE-2018-19320)

 - The GPCIDrv and GDrv low-level drivers in GIGABYTE APP Center v1.05.21 and earlier, AORUS GRAPHICS ENGINE before 1.57, XTREME GAMING ENGINE before 1.26, and OC GURU II v2.08 expose functionality to read and write arbitrary physical memory. This could be leveraged by a local attacker to elevate privileges. (CVE-2018-19321)

 - The GPCIDrv and GDrv low-level drivers in GIGABYTE APP Center v1.05.21 and earlier, AORUS GRAPHICS ENGINE before 1.57, XTREME GAMING ENGINE before 1.26, and OC GURU II v2.08 expose functionality to read/write data from/to IO ports. This could be leveraged in a number of ways to ultimately run code with elevated privileges.
 (CVE-2018-19322)

 - The GDrv low-level driver in GIGABYTE APP Center v1.05.21 and earlier, AORUS GRAPHICS ENGINE before 1.57, XTREME GAMING ENGINE before 1.26, and OC GURU II v2.08 exposes functionality to read and write Machine Specific Registers (MSRs). (CVE-2018-19323)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
