CVE-2017-2441
A use-after-free vulnerability allows remote attackers to execute arbitrary code via a crafted C++ app that is mishandled during demangling.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.71%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
