Double free vulnerability in the gdImageWebPtr function in the GD Graphics Library (aka libgd) before 2.2.4 allows remote attackers to have unspecified impact via large width and height values.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.49%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
