Patch Tuesday, October 2019

October 08, 2019 3 minutes read Karl Sigler

Microsoft’s security update for the month of October is one of the lightest patch Tuesdays of the year with the release of only 60 CVEs. However, it still packs a punch with 9 “Critical” CVEs and the remaining 51 CVEs are rated as “Important”. The good news is that none of these CVEs have publicly available exploits or been seen yet exploited in the wild.  Additionally, there are no rollup patch for Adobe Flash which is very uncommon. However, it shouldn’t be ruled out possibly an out-of-band roll-out for Adobe Flash later this month.

One of the most severe vulnerabilities on the “Critical” list could allow a Remote Desktop Protocol (RDP) server running specifically crafted code to achieve Remote Code Execution (RCE) on a Windows RDP client known as CVE-2019-1333.  Unlike the infamous BlueKeep RDP vulnerability (CVE- 2019-0708), this affects the RDP client and requires user interaction for an attack to be successful.  An attacker could exploit this vulnerability by convincing a victim to connect to a malicious RDP server. 

Similar to previous months, a slew of "Critical" vulnerabilities has been patched affecting various scripting engines embedded in a variety of Microsoft products.  While it has become the norm for these to become included in monthly releases, these still shouldn’t be taken lightly.  In late September, Microsoft released an out-of-band patch for a 0-day affecting the Internet Explorer scripting engine (CVE-2019-1367).

On the "Important" list, there are 20 CVEs that could allow an elevation of privileges for Microsoft products. This should be sufficient reason to update ASAP since affected products include the Windows platform, Microsoft IIS Server and SharePoint.  Another notable vulnerability on the list is a denial of service vulnerability affecting the Windows RDP.

Have a great day and happy patching!
