<A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A>
<UL>
<li> Updated to use Automake 1.12.4. Avoids security problem with
'make distcheck' (CVE-2012-3386).

<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A>
<UL>
<li> Various memory buffer access fixes.
<li> Fix handling when writing RGBA jpeg compressed imagery
(<A HREF="http://trac.osgeo.org/gdal/ticket/4732">http://trac.osgeo.org/gdal/ticket/4732</A>).
<li> Fix to work properly with IJG JPEG 7+.
<li> New functions TIFFFieldTag(), TIFFFieldName(),
TIFFFieldDataType(), TIFFFieldPassCount(), TIFFFieldReadCount(),
TIFFFieldWriteCount() to use as external accessors for the opaque
type TIFFField.
<li> Fix bug rewriting image tiles in a compressed
file (<A HREF="http://trac.osgeo.org/gdal/ticket/4771">http://trac.osgeo.org/gdal/ticket/4771</A>).
<li> Add TIFF/FX tag support in libtiff.

<A NAME="tools"><B><FONT SIZE=+3>C</FONT>HANGES IN THE TOOLS:</B></A>
<UL>
<li> tiff2pdf: Fail when TIFFSetDirectory() fails. This prevents
core dumps or perhaps even arbitrary code execution when processing
a corrupt input file (CVE-2012-3401).
<li> tiff2pdf: Fix two places where t2p_error didn't get set after a
malloc failure. No crash risk AFAICS, but the program might not
report exit code 1 as desired.
