CVE-2018-14551

The ReadMATImageV4 function in coders/mat.c in ImageMagick 7.0.8-7 uses an
uninitialized variable, leading to memory corruption.

Comment 1 Petr Gajdos 2018-08-06 14:58:39 UTC 
There is no testcase.

ReadMATImageV4() code is only in 15/ImageMagick and 12/ImageMagick, not in 11/ImageMagick or */GraphicsMagick.

15/ImageMagick and 12/ImageMagick does not touch status variable outside the loop in question, i. e. there is no 'if (status == MagickFalse)' code after the loop, which the upstream report is refering to.

I think we are not affected.
