CVE-2018-20004
It is a stack-based buffer overflow in mxml_write_node in mxml-file.c via vectors involving a double-precision floating point number and the '<order type="real">' substring, as demonstrated by testmxml.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.02%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
