CVE-2018-11593
Espruino before 1.99 allows attackers to cause a denial of service (application crash) and potential Information Disclosure with a user crafted input file via a Buffer Overflow during syntax parsing because strncpy is misused in jslex.c.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.23%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
