CVE-2016-6207
Integer overflow in the _gdContributionsAlloc function in gd_interpolation.c in GD Graphics Library (aka libgd) before 2.2.3 allows remote attackers to cause a denial of service (out-of-bounds memory write or memory consumption) via unspecified vectors.
Does this matter?
Lower severity and a low EPSS score (6.26%). Track it; it rarely justifies an emergency change on its own.
