Description Josh Bressers 2005-03-04 16:52:52 UTC 
+++ This bug was initially created as a clone of Bug #150323 +++

This issue consists of two bugs:

- conversion from and to quantum, it probably worked only for quantumdepth=8,
  but ImageMagick was compiled with quantumdepth=16.
  The attached patch fixes it.

- The function ReadBlobByte returns values in range 0-255 or (int)-1 on EOF.
  The return value -1 is not checked on many places. The patch
  adds some type conversion, so that it does not crash on issue3.psd.
  However it could crash elsewhere.

The patch for this issue is attachment 111669 [details]
The demo exploit for this issue is attachment 111670 [details]
