CVE-2018-5784 (opens in a new tab)How to fix?
Upgrade Debian:9 tiff to version 4.0.8-2+deb9u4 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream tiff package and not the tiff package as distributed by Debian.
See How to fix? for Debian:9 relevant fixed versions and status.
In LibTIFF 4.0.9, there is an uncontrolled resource consumption in the TIFFSetDirectory function of tif_dir.c. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted tif file. This occurs because the declared number of directory entries is not validated against the actual number of directory entries.
