CVE-2018-12698
demangle_template in cplus-dem.c in GNU libiberty, as distributed in GNU Binutils 2.30, allows attackers to trigger excessive memory consumption (aka OOM) during the "Create an array for saving the template argument values" XNEWVEC call.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.61%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
