* libtiff/tif_dirinfo.c, tif_dirread.c: add _TIFFCheckFieldIsValidForCodec(),
|
|
||||||
and use it in TIFFReadDirectory() so as to ignore fields whose tag is a
|
|
||||||
codec-specified tag but this codec is not enabled. This avoids TIFFGetField()
|
|
||||||
to behave differently depending on whether the codec is enabled or not, and
|
|
||||||
thus can avoid stack based buffer overflows in a number of TIFF utilities
|
|
||||||
such as tiffsplit, tiffcmp, thumbnail, etc.
