CVE-2018-16420

Estado: ModificadaMedia (6.6)—

Several buffer overflows when handling responses from an ePass 2003 Card in decrypt_response in libopensc/card-epass2003.c in OpenSC before 0.19.0-rc1 could be used by attackers able to supply crafted smartcards to cause a denial of service (application crash) or possibly have unspecified other impact.
