CVE-2016-9643
The regex code in Webkit 2.4.11 allows remote attackers to cause a denial of service (memory consumption) as demonstrated in a large number of ($ (open parenthesis and dollar) followed by {-2,16} and a large number of +) (plus close parenthesis).
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.07%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
