"The Microsoft Visual Studio Products are missing a security
update. It is, therefore, affected by the following
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. (CVE-2019-0537)
- A remote code execution vulnerability exists in Visual
Studio when the C++ compiler improperly handles specific
combinations of C++ constructs. 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.
Exploitation of the vulnerability requires that a user
open a specially crafted file which was compiled with
an affected version of Visual Studio. In an email
attack scenario, an attacker could exploit the
vulnerability by sending a specially crafted project,
or resource file, to the user and convince the user to
open the file. (CVE-2019-0546)");
