"The Microsoft Visual Studio Products are missing a security
update. It is, therefore, affected by the following
vulnerability :

  - A remote code execution vulnerability exists in Visual Studio
    software when the software fails to check the source markup of a
    file. An attacker who successfully exploited the vulnerability
    could run arbitrary code in the context of the current user. If
    the current user is logged on with administrative user rights, an
    attacker 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. (CVE-2019-0613)

  - A vulnerability exists in certain .Net Framework API's and Visual
    Studio in the way they parse URL's. An attacker who successfully
    exploited this vulnerability could use it to bypass security
    logic intended to ensure that a user-provided URL belonged to a
    specific hostname or a subdomain of that hostname. This could be
    used to cause privileged communication to be made to an untrusted
    service as if it was a trusted service. To exploit the
    vulnerability, an attacker must provide a URL string to an
    application that attempts to verify that the URL belongs to a
    specific hostname or to a subdomain of that hostname. The
    application must then make an HTTP request to the
    attacker-provided URL either directly or by sending a processed 
    version of the attacker-provided URL to a web browser.
