CVE-2016-6911
The dynamicGetbuf function in the GD Graphics Library (aka libgd) before 2.2.4 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted TIFF image.
Does this matter?
Lower severity and a low EPSS score (1.76%). Track it; it rarely justifies an emergency change on its own.
