Asus Aura Sync and Gigabyte Xtreme Software contain vulnerabilities

A security company called SecureAuth shares word that that two drivers from Asus and also two from Gigabyte contain vulnerabilities. The drivers come bundled with tools that companies provide for motherboards and video cards.

In total, there are seven vulnerabilities affecting five software products, and researchers wrote exploit code for each of them. Many of them might still be unaddressed. Two of the vulnerable drivers are installed by the Aura Sync software (v1.07.22 and earlier) from ASUS and the flaws they carry can be exploited for local code execution reports Dutch-based tweakers.net via bleeping computer:

The vulnerabilities lead to privilege escalation via software like the GIGABYTE App Center (v1.05.21 and below), AORUS Graphics Engine (v1.33 and below), the XTREME Engine utility (v1.25 and earlier), and OC Guru II (v2.08). The vulnerabilities are tagged under CVE-2018-18535, CVE-2018-18536 and CVE-2018-1853. The first and last allow the execution of code with elevated rights, the second can lead to the reading and writing of data via the I/O ports. ASUS has been informed in November last year. In April, Asus released a new version of Aura Sync, but it only fixed two of the three problems, according to SecureAuth.

Vulnerable Packages

ASUS Aura Sync v1.07.22 and previous versions

The vulnerabilities in Gigabyte 's gpcidrv and gdrv drivers are CVE-2018-19320, CVE-2018-19321, CVE-2018-19322 and CVE-2018-19323. This driver supplies the company with the Gigabyte App Center, Aorus Graphic Engine, Xtreme Gaming Engine and OC Guru II. The vulnerabilities make it possible, among other things, to take over a system. There is a proof-of-concept that performs read and write actions on virtual memory and causes a system crash. On April 24th Gigabyte was notified, but the company had released a new version of the software on July 16th that was no longer affected.

Vulnerable Packages

GIGABYTE APP Center v1.05.21 and previous
AORUS GRAPHICS ENGINE v1.33 and previous
XTREME GAMING ENGINE v1.25 and previous
OC GURU II v2.08

"In mei 2018 zou Gigabyte op de hoogte gebracht zijn, maar het bedrijf zou gemeld hebben dat zijn producten niet getroffen zijn door de kwetsbaarheden." - tweakers.net
"In May 2018, Gigabyte would have been notified, but the company would have reported that its products were not affected by the vulnerabilities." - Google translate

Google translate seems to have completely changed the meaning to imply that Gigabyte was not contacted.
"would have been, but" = "wasn't" + (excuse)
A more accurate translation can be derived from the bleepingcomputer story.
-SecureAuth contacted GIGABYTE on April 24, 2018-
-Gigabyte responded on April 30, 2018
-in May 2018 Gigabyte asked for details and guidance to confirm the vulnerabilities
-Ultimately Gigabyte claimed their software was not affected

IMO it should read like this:
"On April 24th Gigabyte was notified, but the company had released a new version of the software on July 16th that was no longer affected."
