Microsoft Windows GDI+ EMF EmfPlusFont Object denial of service
| win-gdi-emfplusfont-dos (49438) |  Medium Risk |
Description:
The Microsoft Windows GDI+ (Gdiplus.dll) is vulnerable to a denial of service, caused by an off-by-one error in the GpFont.SetData() function when processing EMF image files. By persuading a victim to open a specially-crafted Enhanced Metafile (EMF) image file containing a malformed font length value in the EmfPlusFont Object record, a remote attacker could exploit this vulnerability and cause the affected application to crash.
