Fix heap-based buffer overflow in TIFFFillStrip():
|
||||
|
||||
http://bugzilla.maptools.org/show_bug.cgi?id=2608
|
||||
|
||||
2016-12-03 Even Rouault <even.rouault at spatialys.com>
|
||||
|
||||
* libtiff/tif_dirread.c: modify ChopUpSingleUncompressedStrip() to
|
||||
instanciate compute ntrips as TIFFhowmany_32(td->td_imagelength,
|
||||
rowsperstrip),
|
||||
instead of a logic based on the total size of data. Which is faulty is
|
||||
the total size of data is not sufficient to fill the whole image, and
|
||||
thus
|
||||
results in reading outside of the StripByCounts/StripOffsets arrays
|
||||
when
|
||||
using TIFFReadScanline().
|
||||
Reported by Agostino Sarubbo.
|
||||
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2608.
|
||||
|
||||
* libtiff/tif_strip.c: revert the change in TIFFNumberOfStrips() done
|
||||
for http://bugzilla.maptools.org/show_bug.cgi?id=2587 / CVE-2016-9273
|
||||
since
|
||||
the above change is a better fix that makes it unnecessary.
