La interfaz Graphics Device Interface (GDI) de Windows en Microsoft Windows Server 2008 SP2 y R2 SP1; Windows 7 SP1; Windows 8.1; Windows Server 2012 Gold y R2; Windows RT 8.1; Windows 10 Gold, 1511, 1607, 1703 y Server 2016; Office 2007 SP3; Office 2010 SP2; Word Viewer; Office para Mac 2011 y 2016; Skype for Business 2016; Lync 2013 SP1; Lync 2010; Lync 2010 Attendee; y Live Meeting 2007 Add-in y Console permite que un atacante autenticado recupere información de un sistema objetivo mediante una aplicación especialmente manipulada. Esto también se conoce como "Windows GDI+ Information Disclosure Vulnerability."

This vulnerability allows remote attackers to disclose sensitive information on vulnerable installations of Microsoft Windows. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the handling of bitmap image data in graphics files. The issue results from the lack of proper validation of user-supplied data, which can result in a read outside an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process.
