Security readout for executives and security teams
This is a Microsoft Visio privilege escalation issue caused by unsafe DLL library loading. A user can be tricked into running or opening crafted content, allowing an attacker-controlled local application to gain the user's privileges on systems with affected Visio or Visio Viewer versions. Exposure is most likely on endpoints with Microsoft Visio 2007 SP3, 2010 SP2, 2013 SP1, 2016, Visio Viewer 2007 SP3, or Visio Viewer 2010 installed. Servers are less likely affected unless these desktop applications are present. Treat this as high priority where legacy Visio or Visio Viewer exists. It is not a remote worm-style issue, but KEV status means exploitation has been observed and unremediated desktop estates can create material endpoint compromise risk. Mitigation focus: Apply Microsoft guidance and security updates from MS16-070.; Inventory and remediate affected Visio and Visio Viewer installations.; Remove vulnerable Visio or Viewer installations where not business required..
