Microsoft CVE-2019-0537: Microsoft Visual Studio Information Disclosure Vulnerability

An information disclosure vulnerability exists when Visual Studio improperly discloses arbitrary file contents if the victim opens a malicious .vscontent file. An attacker who took advantage of this information disclosure could view arbitrary file contents from the computer where the victim launched Visual Studio.
To take advantage of the vulnerability, an attacker would need to trick a user into opening a malicious .vscontent file using a vulnerable version of Visual Studio. An attacker would have no way to force a developer to produce this information disclosure.
The security update addresses the vulnerability by correcting how Visual Studio loads .vscontent files.
