|

|
|

(<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+.
|
|
|
|
|
|
|
|

|
|
|
|
|
TIFFFieldDataType(), TIFFFieldPassCount(), TIFFFieldReadCount(),
|
|
|
|
|
TIFFFieldWriteCount() to use as external accessors for the opaque

type TIFFField.
|
|
|
|
|
|

file (<A HREF="http://trac.osgeo.org/gdal/ticket/4771">http://trac.osgeo.org/gdal/ticket/4771</A>).

<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.
