Security Advisory Notices

CVE-2019-1077 Visual Studio Extension Auto Update Vulnerability

An elevation of privilege vulnerability exists when the Visual Studio Extension auto-update process improperly performs certain file operations. An attacker who successfully exploited this vulnerability could delete files in arbitrary locations. To exploit this vulnerability, an attacker would require unprivileged access to a vulnerable system. The security update addresses the vulnerability by securing locations the Visual Studio Extension auto-update performs file operations in.

CVE-2019-1075 ASP.NET Core Spoofing Vulnerability

A spoofing vulnerability exists in ASP.NET Core that could lead to an open redirect. An attacker who successfully exploited the vulnerability could redirect a targeted user to a malicious website. To exploit the vulnerability, an attacker could send a link that has a specially crafted URL and convince the user to click the link.

The security update addresses the vulnerability by correcting how ASP.NET Core parses URLs. Details can be found in the .NET Core release notes.

CVE-2019-1113 WorkflowDesigner XOML deserialization allows code execution

A XOML file referencing certain types could cause random code to be executed when the XOML file is opened in Visual Studio. There is now a restriction on what types are allowed to be used in XOML files. If a XOML file containing one of the newly unauthorized types is opened, a message is displayed explaining that the type is unauthorized.
