"Brief introduction 

CVE-2018-17000

A NULL pointer dereference in the function _TIFFmemcmp at tif_unix.c
(called from TIFFWriteDirectoryTagTransferfunction) allows an attacker
to cause a denial of service through a crafted tiff file. This
vulnerability can be triggered by the executable tiffcp.

CVE-2018-19210

There is a NULL pointer dereference in the TIFFWriteDirectorySec
function in tif_dirwrite.c that will lead to a denial of service
attack, as demonstrated by tiffset.

CVE-2019-7663

An Invalid Address dereference was discovered in
TIFFWriteDirectoryTagTransferfunction in libtiff/tif_dirwrite.c,
affecting the cpSeparateBufToContigBuf function in tiffcp.c. Remote
attackers could leverage this vulnerability to cause a
denial of service via a crafted tiff file.

We believe this is the same as CVE-2018-17000 (above).

For Debian 8 'Jessie', these problems have been fixed in version
4.0.3-12.3+deb8u8.

We recommend that you upgrade your tiff packages.
