Two vulnerabilities have been identified in Microsoft Windows, which could be exploited by remote attackers to cause a denial of service or take complete control of an affected system.
The first issue is caused by a heap overflow error in the graphics device interface (GDI) CreateDIBPatternBrushPt function when processing a malformed header in a specially crafted Windows Metafile (WMF) or Enhanced Metafile (EMF) image file, which could be exploited by attackers to execute arbitrary code by tricking a user into visiting a specially crafted web page.
The second vulnerability is caused by a stack overflow error in the graphics device interface (GDI) when processing a malformed file name parameter in a specially crafted Enhanced Metafile (EMF) image file, which could be exploited by attackers to execute arbitrary code by tricking a user into visiting a specially crafted web page.
