In coders/psd.c in ImageMagick 7.0.7-0 Q16, a DoS in ReadPSDLayersInternal() due to lack of an EOF (End of File) check might cause huge CPU consumption. When a crafted PSD file, which claims a large length field in the header but does not contain sufficient backing data, is provided, the loop over length would consume huge CPU resources, since there is no EOF check inside the loop.
The product performs an iteration or loop without sufficiently limiting the number of times that the loop is executed.
