Description Andrej Nemec 2017-09-08 13:23:13 UTC

The ReadSUNImage function in coders/sun.c in GraphicsMagick 1.3.26 has an issue where memory allocation is excessive because it depends only on a length field in a header. This may lead to denial of service in the MagickMalloc function in magick/memory.c.

Upstream patch:
