Hi,

the following vulnerability was published for tiff. Since it only
leads to a crash in cli tool we marked it as unimportant in the
security-tracker, still filling a bug to keep track of a fix if it
lands upstream.

CVE-2017-17095[0]:
| tools/pal2rgb.c in pal2rgb in LibTIFF 4.0.9 allows remote attackers to
| cause a denial of service (TIFFSetupStrips heap-based buffer overflow
| and application crash) or possibly have unspecified other impact via a
| crafted TIFF file.

If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.

Please adjust the affected versions in the BTS as needed, only
unstable has been checked.
