CVE-2018-16427
Various out of bounds reads when handling responses in OpenSC before 0.19.0-rc1 could be used by attackers able to supply crafted smartcards to potentially crash the opensc library using programs.
Does this matter?
Lower severity and a low EPSS score (0.49%). Track it; it rarely justifies an emergency change on its own.
