"Two vulnerabilities have been discovered in the libtiff library and
the included tools, which may result in denial of service or the
execution of arbitrary code.

CVE-2017-9936

A crafted TIFF document can lead to a memory leak resulting in a
remote denial of service attack.

CVE-2017-10688

A crafted input will lead to a remote denial of service attack.

For Debian 7 'Wheezy', these problems have been fixed in version
4.0.2-6+deb7u15.

We recommend that you upgrade your tiff packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
