[magick-users] ImageMagick-6.0.4-2, fix for PNG vulnerability

[yarrow at studio.imagemagick.org]

There will be an announcement shortly concerning a vulnerability in the
PNG library.  Although the fix is in the PNG library itself, Glenn has
contributed a patch that will help stop the exploit within ImageMagick
when using older versions of the library, 1.2.5 and earlier.  We are
currently uploading ImageMagick-6.0.4-2 that has this patch.  The only
other change in this release is automake has been upgraded from 1.8.6
to 1.9.  Look for an updated Windows source/binary distribution late this
evening.
