Patch Tuesday: Microsoft Security Bulletin Summary for June 2019

Today, Microsoft Patch Tuesday June 2019 has released its monthly set of security advisories for vulnerabilities that have been identified and addressed in various products. This month’s advisory release addresses 88 new vulnerabilities, with 21 of them rated critical, 66 are rated Important and 1 is listed as Moderate in severity. These vulnerabilities impact Servicing Stack Updates, Windows Kernel, Adobe Flash Player, Microsoft Devices, Kerberos, Microsoft Graphics Component, Microsoft JET Database Engine, Microsoft Scripting Engine, Skype for Business and Microsoft Lync, Microsoft Edge, Internet Explorer, Microsoft Exchange Server, Microsoft Office, Microsoft Office SharePoint, etc.

1) CVE-2019-1069 – An elevation of privilege vulnerability exists in the way the Task Scheduler Service validates certain file operations. An attacker who successfully exploited the vulnerability could gain elevated privileges on a victim system. To exploit the vulnerability, an attacker would require unprivileged code execution on a victim system.

2)CVE-2019-1064 – An elevation of privilege vulnerability exists when Windows AppX Deployment Service (AppXSVC) improperly handles hard links. An attacker who successfully exploited this vulnerability could run processes in an elevated context. An attacker could then install programs; view, change or delete data. To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system.

3)CVE-2019-1053 – An elevation of privilege vulnerability exists when the Windows Shell fails to validate folder shortcuts. An attacker who successfully exploited the vulnerability could elevate privileges by escaping a sandbox. To exploit this vulnerability, an attacker would require unprivileged execution on the victim system.

4)CVE-2019-0973 – An elevation of privilege vulnerability exists in the Windows Installer when the Windows Installer fails to properly sanitize input leading to an insecure library loading behavior. A locally authenticated attacker could run arbitrary code with elevated system privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

1) Hyper-V and Office Vulnerabilities: Three remote code execution vulnerabilities, CVE-2019-0620, CVE-2019-0709, and CVE-2019-0722 were found in Hyper-V that would allow an authenticated user to run arbitrary code. Two REC vulnerabilities were found in Word, CVE-2019-1034 and CVE-2019-1035 by Allan Liska, threat intelligence analyst at Recorded Future.

2)NTLM Relay Attack Bug: CVE-2019-1040 and CVE-2019-1019 were found and patched that would allow attackers to remotely execute malicious code on any Windows machine or authenticate to any web server that supports Windows Integrated Authentication (WIA) such as Exchange or ADFS.

None were found being exploited in the wild.
