The WPG parser in ImageMagick before 6.9.4-4 and 7.x before 7.0.1-5, when a
memory limit is set, allows remote attackers to have unspecified impact via
vectors related to the SetImageExtent return-value check, which trigger (1)
a heap-based buffer overflow in the SetPixelIndex function or an invalid
write operation in the (2) ScaleCharToQuantum or (3) SetPixelIndex
functions.
