Microsoft Patch Tuesday, June 2017

June 13, 2017 3 minutes read SpiderLabs Researcher

For the June 2017 Patch Tuesday Microsoft is releasing 97 CVEs, nearly double the number of vulnerabilities patched in May. The release includes patches for 19 CVEs rated "Critical", 76 rated "Important" and one vulnerability each rated "Moderate" and "Low". The release also includes two roll up packages of multiple patches. The seemingly ever present one for Adobe Flash and one "defense-in-depth" update for Microsoft SharePoint. Across them all these vulnerabilities there are security updates for the following software and services:

  • Microsoft Edge Browser
  • Microsoft Windows
  • Microsoft Office
  • Microsoft Scripting Engine
  • Windows OLE
  • Microsoft GDI and Uniscribe engines
  • Adobe Flash Player
  • Microsoft SharePoint
  • Windows Search
  • Internet Explorer

Seven of the vulnerabilities rated "Critical" affect the Microsoft Scripting Engine typically used to process javascript and VBScript while web browsing. There are also a lot of the other usual suspects in the "Critical" list like the Windows PDF engine and remote code execution (RCE) vulnerabilities that can be triggered with malicious fonts in the Uniscribe and GDI engines. Relatively new to the list are RCE vulnerabilities in OLE (CVE-2017-8487), LNK shortcuts (CVE-2017-8464) and the Windows Search function (CVE-2017-8543). The Windows Search vulnerability doesn't require any authenticated access or social engineering attacks in order to trick a logged in user to exploit themselves. An attacker would only need an SMB connection to a target machine in order to run arbitrary code in the SYSTEM user context.

Vulnerabilities covered by the "Important" rating include multiple RCE vulnerabilities in Microsoft Office, so make sure you are updated before opening that Office document you received as an email attachment. There are also dozens of privilege escalation vulnerabilities patched in the "Important" list. While typically not directly a threat to a system exploits for these types of vulnerabilities are often paired with code execution vulnerabilities to gain code at the administrative or system levels.
