CVE-2017-8464 LNK Remote Code Execution Vulnerability
A remote code execution vulnerability exists in Microsoft Windows that could allow remote code execution if a .LNK file is processed.
An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. 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 attacker could present to the user a removable drive, or remote share, that contains a malicious .LNK file and an associated malicious binary. When the user opens this drive(or remote share) in Windows Explorer, or any other application that parses the .LNK file, the malicious binary will execute code of the attacker’s choice, on the target system.
This security update addresses the vulnerability by correcting the processing of shortcut LNK references.
CVE-2017-8543 Windows Search Remote Code Execution Vulnerability
A remote code execution vulnerability exists when Windows Search handles objects in 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.
To exploit the vulnerability, the attacker could send specially crafted messages to the Windows Search service. An attacker with access to a target computer could exploit this vulnerability to elevate privileges and take control of the computer. Additionally, in an enterprise scenario, a remote unauthenticated attacker could remotely trigger the vulnerability through an SMB connection and then take control of a target computer.
This security update addresses the vulnerability by correcting how Windows Search handles objects in memory.
CVE-2017-8552 Win32k Elevation of Privilege Vulnerability
An elevation of privilege vulnerability exists when the Windows kernel-mode driver 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 that could exploit the vulnerability and take control of an affected system.
This update addresses the vulnerability by correcting how the Windows kernel-mode driver handles objects in memory.
