+	<p>libpng developers report:</p>
+	<blockquote cite="http://libpng.sourceforge.net/Advisory-1.2.26.txt">
+	  <p>Tavis Ormandy advised us of a bug in libpng in its handling of
+	    unknown chunks with zero data length.</p>
+	  <p>We have examined the report and find that the bug exists in all
+	    libpng versions since 1.0.6.  It only manifests itself when all
+	    three of the following conditions exist:</p>
+	  <p>1. The application is loaded with libpng-1.0.6 through 1.0.32,
+	    libpng-1.2.0 through 1.2.26, or libpng-1.4.0beta01 through
+	    libpng-1.4.0beta19, and</p>
+	  <p>2. libpng was built with PNG_READ_UNKNOWN_CHUNKS_SUPPORTED
+	    or with PNG_READ_USER_CHUNKS_SUPPORTED (both are active in default
+	    libpng installations), and</p>
+	  <p>3. the application includes either a call to 
+	    png_set_read_user_chunk_fn(png_ptr, user_ptr, callback_fn) or a 
+	    call to png_set_keep_unknown_chunks(png_ptr, keep, list, N) with 
+	    keep = PNG_HANDLE_CHUNK_IF_SAFE (2) or keep = 
+	    PNG_HANDLE_CHUNK_ALWAYS (3)</p>
+	  <p>We believe this is a rare circumstance.  It occurs in "pngtest"
+	    that is a part of the libpng distribution, in pngcrush, and in
+	    recent versions of ImageMagick (6.2.5 through 6.4.0-4).  We are
+	    not aware of any other vulnerable applications.</p>
+	  <p>When an application with the bug is run, libpng will generate
+	    spurious warning messages about a CRC error in the zero-length 
+	    chunk and an out-of-memory condition, unless warnings are being
+	    suppressed. There is not actually a memory overflow, but the NULL
+	    pointer returned from the memory allocator when it tries to 
+	    generate a zero-length buffer for the chunk data triggers the 
+	    warning. Later, there may be an error when the application tries 
+	    to free the non-existent buffer. This has been observed to cause a 
+	    segmentation violation in pngtest.</p>
+	  <p>Libpng-1.2.27 and later, and 1.0.33 and later, will not be 
+	    vulnerable. These are in beta and will be released on or about 
+	    April 30, 2008. Libpng-1.2.27beta01, which was released on April 
+	    12, is also not vulnerable.</p>
