August Patch Tuesday: Is RDP Worth the Risk?

Microsoft has released almost 100 updates today making this one of the largest Patch Tuesday updates of the year.

August Patch Tuesday Has Arrived

Microsoft has released almost 100 updates today, 93 in total with 29 rated Critical and 64 Important. This is one of the largest releases this year and brings a few key updates to be aware of.

Remote Desktop Services

CVE-2019-1181, CVE-2019-1182, CVE-2019-1222 & CVE-2019-1226

There is no doubt that right now Windows RDS (used by remote desktop) has been exposed for a plethora of network hacks and global data thefts. It’s also one of the chosen weaknesses used to spread ransomware.

Although not technically a Zero Day vulnerability, we recommend this CVSS score 9.8 vulnerability be your highest priority in this release. Robert Brown, Director of Services said, “This year alone, this is one technology which keeps getting exposed, and is a favorite amongst the hackers. Although there are no known exploits (right now), this vulnerability is recognized by Microsoft as exploitation more likely, hence if you are using RDP this needs to be patched right away. Now is the time to decide whether RDP is worth the risk, or if there is another technology which offers better security?”

Microsoft Graphics Remote Code Execution Vulnerability

CVE-2019-1144, CVE-2019-1145, CVE-2019-1149, CVE-2019-1150, CVE-2019-1151 & CVE-2019-1152

This vulnerability carries a CVSS score of 8.8 and impacts almost every Windows operating system. We have seen vulnerabilities like these released as “Zero Day” in previous releases due to the security issues with Windows fonts. Windows font library improperly handles specially crafted embedded fonts, an attacker who successfully exploited the vulnerability could take control of the whole system, including installing applications and creating new accounts with full user rights.

Adobe Updates

Adobe has released 3 updates for Adobe Reader which resolves a grand total of 119 vulnerabilities. APSB19-41 has been given a Priority 2 which means Adobe recommend this be deployed within 30 as they have an elevated risk.

No Updates are Public or Exploited

As of the release schedule, none of the Microsoft vulnerabilities are either Publicly Disclosed or known to be Exploited.
