CVE-2017-7790
On Windows systems, if non-null-terminated strings are copied into the crash reporter for some specific registry keys, stack memory data can be copied until a null is found.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.70%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
