CVE-2018-12405
Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.20%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description

Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code.
