"Multiple vulnerabilities have been discovered in the libtiff library
and the included tools, which may result in denial of service :

CVE-2017-11613

Ddenial of service vulnerability in the TIFFOpen function. A crafted
input will lead to a denial of service attack and can either make the
system hand or trigger the OOM killer.

CVE-2018-5784

There is an uncontrolled resource consumption in TIFFSetDirectory
function of src/libtiff/tif_dir.c, which can cause denial of service
through a crafted tif file.

For Debian 7 'Wheezy', these problems have been fixed in version
4.0.2-6+deb7u21.

We recommend that you upgrade your tiff packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
