DLA-693-2 tiff -- LTS security update

Date Reported:
07 Feb 2017
Affected Packages:
Security database references:
In the Debian bugtracking system: Bug 852610.
More information:

Version 4.0.2-6+deb7u7 introduced changes that resulted in libtiff being unable to write out tiff files when the compression scheme in use relies on codec-specific TIFF tags embedded in the image.

This problem manifested itself with errors like those:
$ tiffcp -r 16 -c jpeg sample.tif out.tif
_TIFFVGetField: out.tif: Invalid tag Predictor (not supported by codec).
_TIFFVGetField: out.tif: Invalid tag BadFaxLines (not supported by codec).
tiffcp: tif_dirwrite.c:687: TIFFWriteDirectorySec: Assertion `0' failed.

For Debian 7 Wheezy, these problems have been fixed in version 4.0.2-6+deb7u10.

We recommend that you upgrade your tiff packages.
