Microsoft Tuesday Patches 39 Vulnerabilities including 9 critical vulnerabilities and 30 other important flaws.
Microsoft also fixes the issues in its browsers Internet Explorer and Edge. Also fixes Microsoft Windows, Office and PowerPoint which have vulnerable to exploit.
However, “the attacker would first have to log onto the system then run a specially crafted application to take control of the affected system,” said Chris Goettl, director of product management, security, Ivanti.
What CVE-2018-8611 | Windows Kernel Elevation of Privilege Vulnerability
An elevation of privilege vulnerability exists when the Windows kernel fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data, or create new accounts with full user rights.
To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application to take control of an affected system.
The update addresses the vulnerability by correcting how the Windows kernel handles objects in memory.
“This vulnerability exists in all currently supported Windows Operating systems from Windows 7 to Server 2019,” Goettl said. “Exploitation has been detected on older OSs already, but the Exploitability Index is rated as a 1 for Windows 10 and Server 2019.”
Another CVE-2018-8634 | Microsoft Text-To-Speech Remote Code Execution Vulnerability Fixed.
A remote code execution vulnerability exists in Windows where Microsoft text-to-speech fails to properly handle objects in the memory. An attacker who successfully exploited this vulnerability could take control of the affected system. An attacker could then install programs, view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
The security update addresses the vulnerability by correcting how the Microsoft text-to-speech handles objects in the memory.
