Security Vulnerabilities - CVEs Published In June 2019
An information disclosure vulnerability exists when the Windows GDI component improperly discloses the contents of its memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the user’s system.
There are multiple ways an attacker could exploit the vulnerability, such as by convincing a user to open a specially crafted document, or by convincing a user to visit an untrusted webpage.
The security update addresses the vulnerability by correcting how the Windows GDI component handles objects in memory.

An elevation of privilege vulnerability exists when the Windows Common Log File System (CLFS) driver improperly handles objects in memory. An attacker who successfully exploited this vulnerability could run processes in an elevated context.
To exploit the vulnerability, an attacker would first have to log on to the system, and then run a specially crafted application to take control over the affected system.
The security update addresses the vulnerability by correcting how CLFS handles objects in memory.

A remote code execution vulnerability exists when the Microsoft Speech API (SAPI) improperly handles text-to-speech (TTS) input. The vulnerability could corrupt memory in a way that enables an attacker to execute arbitrary code in the context of the current user.
To exploit the vulnerability, an attacker would need to convince a user to open a specially crafted document containing TTS content invoked through a scripting language.
The update address the vulnerability by modifying how the system handles objects in memory.

An elevation of privilege vulnerability exists when the Windows User Profile Service (ProfSvc) improperly handles symlinks. An attacker who successfully exploited this vulnerability could delete files and folders in an elevated context.
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 delete files or folders of their choosing.
The security update addresses the vulnerability by correcting how the Windows User Profile Service handles symlinks.

A remote code execution vulnerability exists in the way the scripting engine handles objects in memory in Microsoft browsers. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
In a web-based attack scenario, an attacker could host a specially crafted website designed to exploit the vulnerability through a Microsoft browser and then convince a user to view the website. An attacker could also embed an ActiveX control marked "safe for initialization" in an application or Microsoft Office document that hosts the browser rendering engine. The attacker could also take advantage of compromised websites and websites that accept or host user-provided content or advertisements. These websites could contain specially crafted content that could exploit the vulnerability.
The security update addresses the vulnerability by modifying how the scripting engine handles objects in memory.
