Summary

SumatraPDF: stack buffer overflow while processing EXIF Orientation metadata

Details

SumatraPDF is a multi-format reader for Windows. In 3.6.1 and earlier, MaybeFlipBitmap() asks GDI+ to read the attacker-controlled PropertyTagOrientation size through GetPropertyItem() while supplying only a fixed 64-byte buf on the stack. Opening a crafted TIFF with enough EXIF Orientation values can cause attacker-selected bytes to overwrite stack control data, while tested builds terminate through the stack cookie check. No broader impact is claimed beyond the advisory-supported conditions. No fixed version is available as of this review.
