Patch Tuesday, June 2019

For June's Patch Tuesday, Microsoft is releasing four advisories and patches for a massive 88 CVEs, the largest Patch Tuesday release in well over a year. Twenty-one of those CVEs are rated "Critical," 66 are rated "Important," and one CVE was rated "Moderate." While the majority of the "Critical" rated CVEs affect the various scripting engines embedded in a variety of Microsoft products there are two standouts on that list. First are three separate Remote Code Execution vulnerabilities for Microsoft's Hyper-V virtualization platform. By exploiting the vulnerability an attacker could escape out of the guest environment and execute arbitrary code under the primary Hyper-V operating system. The second interesting "Critical" vulnerability affects the Microsoft Speech API. If an attacker can convince a victim to open a malicious document, they can invoke the Text-to-Speech function and exploit the vulnerability resulting in the execution of arbitrary code.

The long list of CVEs rated as "Important" includes patches for some of the Privilege Escalation vulnerabilities released as zero days by SandboxEscaper last month. There are also patches for Remote Code Execution vulnerabilities in Microsoft Word as well as patches for Denial of Service vulnerabilities in IIS Server, Skype for Business and Lync Server, Hyper-V and in a variety of the Windows OS.

Without further ado, here is the full list of issues fixed.
