CVE-2017-5522
Stack-based buffer overflow in MapServer before 6.0.6, 6.2.x before 6.2.4, 6.4.x before 6.4.5, and 7.0.x before 7.0.4 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via vectors involving WFS get feature requests.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.76%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
