CVE-2014-9766
Integer overflow in the create_bits function in pixman-bits-image.c in Pixman before 0.32.6 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via large height and stride values.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.62%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
