CVE-2018-5784
Remote attackers could leverage this vulnerability to cause a denial of service via a crafted tif file.
Does this matter?
Lower severity and a low EPSS score (2.96%). Track it; it rarely justifies an emergency change on its own.
Description
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.
